(Fig.2) Phonon quasiparticle meaning sound wave or vibration has No physical shape.
Quantum mechanics is unable to explain the normal thermal (or sound ) vibration of material realistically, instead, it relies on fictitious quasiparticle model called phonon that is expressed just as a nonphysical math symbol with No physical figure or shape ( this p.4 ), which cannot be used as practical tools to build useful nano-devices.
This recent phonon quasiparticle paper ↓
p.1-abstract says "We calculate the superconducting critical temperature TC ab initio considering the full phonon (= fictional quasiparticle ) spectral function." ← No mention of practical application, so phonon quasiparticle is useless.
p.3-right shows phonon quasiparticle is just a unphysical math symbols with No concrete shape.
p.4-right-last~p.5-left-1st-paragraph relied on one-pseudo-electron density functional theory based on artificially-chosen pseudo-potential. ← No quantum mechanical prediction.
p.5-right-2nd-last-paragraph says "We use μ* = 0.16 for the Coulomb pseudopotential" ← choosing free parameters means No quantum mechanical prediction.
The 2-3rd, 7th, 14th, 18th, 28th paragraphs of this hyped news say
"Electrons carry electrical energy, while vibrational energy is carried by phonons. Understanding how they interact with each other in certain materials, like in a sandwich of two graphene layers, will (= just speculation ) have implications for future optoelectronic devices (= vague devices, and just hype, fictional phonon has No practical application )."
"Recent work has revealed that graphene layers twisted relative to each other by a small "magic angle" can act as perfect insulator or superconductor. But the physics of the electron–phonon interactions are a mystery (= quantum mechanics failed to understand phonon quasiparticle )"
"Phonons aren't particles like electrons though, they're a (fictional) quasiparticle. Yet, their interaction with electrons in certain materials and how they affect energy loss in electrons has been a mystery."
"the team wanted to learn more about how electrons lose energy in magic-angle twisted bilayer graphene, or MATBG for short."
"especially at ultracold temperatures (specifically below -73°C = impractically-low temperature ). At these temperatures, it's very difficult for electrons to lose energy to phonons, yet it happens in the MATBG."
"As the material is only being studied for a few years, we're still some way from seeing magic-angle twisted bilayer graphene having an impact on society (= still No practical use )"
↑ This research paper ↓
p.1-right-1st~2nd-paragraphs say "In graphene, cooling typically
occurs via the emission of optical and acoustic graphene phonons (= just imagination based on fictional quasiparticle )..
In these systems, a dark exciton (= fictional quasiparticle ) state emerges between van
Hove singularities"
p.3-left-2nd-paragraph says
". In BLG (= nontwisted Bernal bilayer graphene ), the cooling
time increases from 3 to 25 ps as the temperature decreases
from 300 to 5 K, which is expected as it takes longer for hot carriers to couple to phonons at lower temperature due to the reduced phonon occupation. Notably, in MATBG (= magic-angle twisted bilayer graphene ), the
cooling time remains short, around 3 ps, across a broad temperature range (5 to 300 K). This suggests the involvement of
low-energy (fictional) phonons (= an unreasonable leap of logic )"
↑ The time needed to cool graphene from 300 to 5K decreased from 25ps to 3ps depending on the twisted angle between two layers of graphene, which is due to the fictional phonon quasiparticle ? ← Quantum mechanics relying on fictional quasiparticles cannot clarify real mechanism, and No practical use.
p.7-8 This research made No quantum mechanical calculation nor prediction (= No Schrodinger equation nor DFT was used ).
They just used artificially-chosen parameters ( this p.2-3 ).
(Fig.3) ↓ No real magnetic monopole. Berry phase or curvature is just fictitious magnetic field with No real physical meaning and No practical application.
Berry phase is useless fictitious magnetic field.
Magnetic monopole, a hypothetical particle with only one north or south magnetic pole, does Not exist.
Despite this unreal monopole, physicists are trying to use fictitious quasiparticle model to explain and create fake magnetic monopole in various magnetic materials such as spin ice (= unreal spin itself is unseen, only magnetic moment equal to electron's orbital motion can be measured ) in vain.
This fake monopole quasiparticle is Not a real monopole, but just a collection of multiple magnetically-polarized electrons or atoms ( this 4th-last-paragraph ).
Pursuing this fictional meaningless monopole quasiparticle in the current mainstream condensed matter physics clearly obstructs technological innovation, and spawns many unfounded hyped news to hide the unreal and impractical science.
The 1-2nd, 4th, last paragraphs of this hyped news say
"there have been hypotheses of the existence of magnetic monopoles, fundamental particles that are just north or just south. Researchers have Not found them yet"
"Using hematite, the rock equivalent of rust, the researchers discovered that on its surface, peculiar "magnetic configurations (= just magnetic configuration, Not a real monopole )" can emerge. They measured (fictional) quasiparticles – an interaction of sorts that behaves like (= meaning unreal ) a particle for a time."
"These monopoles are a collective state of many spins (= many orbits, correctly ) that twirl around a singularity rather than a single fixed particle (= Not a single real magnetic monopole ), so they emerge through many-body interactions (= fictional monopole quasiparticle just approximately represents a collective magnetic field created by multiple atoms, Not by real monopoles )"
"The measurements were conducted using a diamond needle where the spin of a single electron – its intrinsic angular momentum (= Not by spin but by electron's orbit ) – was used to precisely measure the magnetic field of the material.."
".. Discovering how to manipulate these peculiar quasiparticles might (= just speculation, still useless ) mean better computer technology, with fast and energy-efficient memory logic (= hype, this fictional magnetic monopole has No practical use )."
↑ This research paper ↓
p.3-Fig.1 shows this is Not a real magnetic monopole but just an ordinary molecule consisting of multiple magnetic atoms showing some swirling magnetic field pattern at extremely-low temperature of 4K (= impractically-low temperature ).
p.4-Fig.2 tries to explain some magnetic field pattern by fictional meron quasiparticle.
p.6 No quantum mechanical calculation nor prediction (= No Schrodinger equation nor DFT was used ).
The 5th and 7th paragraphs of this other website say
"Rather, the existence of magnetic monopoles is a collective phenomenon (= Not a single real monopole ) due to the interactions between the atoms and electrons of which spin ice is composed (= fictional monopole quasiparticle is just some magnetic material composed of multiple atoms )."
"The magnetic monopoles are a class of (fictional) quasiparticles that particularly fascinate physicists, while at the same time presenting them with major puzzles. “Quasiparticles exist that appear to be fragments of elementary particles that are normally considered to be indivisible (= quasiaprticle is unreal )".
↑ This research paper on fictional monopole in spin ice ( this ↓ ).
p.1-abstract mentions the fictional fractional electric charge e/3 of quasiparticle, and No mention of practical application of this fictional quasiparticle (= so monopole is useless )
p.1-left mentions 10 (= integer ) Bohr magneton (= μB ) which can be explained by electron's orbit Not by unphysical spin.
p.2-right-(3) fictional magnetic charge Q, which does not really exist.
p.4-6 shows some nonphysical equations with No quantum mechanical calculation nor prediction (= No Schrodinger equation nor DFT was used ).
The current condensed matter physics heavily relies on tons of fictional useless concepts such as Berry phase or Berry curvature which is just fictitious magnetic field (= Not real magnetic field ) generated around imaginary monopole ( this p.1-left, this p.4-1st-paragraph, this p.4-5, this p.1-left ).
This p.12 (or p.32 )-upper says
"The Berry phase is analogous (= No real )
to a magnetic flux, and the quantity... is called the Berry curvature, which is analogous (= Not real ) to a magnetic field.
A good way of thinking about these quantities is to imagine a fictitious
magnetic monopole sitting inside a closed surface."
This p.2-middle-4th-paragraph says
"This phase cannot have any physical
meaning."
↑ As long as the current mainstream physics or quantum mechanics uses these unrealistic concepts, clarifying true atomic mechanism usable for building practical molecular devices is impossible forever.
This recent paper on fictitious Berry phase ↓
p.1-abstract-last just says "Our work provides an opportunity for the study of (unphysical) geometric phases, leading to a variety of observations in light-driven topological phenomena and attosecond solid-state physics (= Not specifying practical use, so the unphysical Berry phase is useless )"
p.2-right-1st-paragraph used fictitious quasi-momentum, and Berry phase is just nonphysical math concept with No physical shape.
p.5-Fig.4 used Circular dichroism HHG spectroscopy, which just measured (classical) laser light response from material ( this p.4 ) for guessing fictitious Berry phase.
This p.6-last-paragraph~p.7 used one-pseudo-electron DFT with PAW (artificially-chosen) pseudo-potential, and The Wannier function-based tight-binding Hamiltonian for fictional Berry phase.
↑ This is Not quantum mechanical prediction, because pseudo-potential and Wannier function must artificially choose various parameters such as energy window ( this p.22, this p.2-right-2nd-paragraph, this-p.11 3rd, last-paragraphs ).
(Fig.4) Skyrmion is just an unstable useless magnetic swirling (= by electron's orbit, Not by unphysical spin )
Quantum mechanics sticks to fictional useless quasiparticle model called skyrmion to express some unstable swirling magnetization patterns (= Not by unphysical spin but by electron's orbit ) transiently generated on materials.
Impractical quantum mechanics can only describe this fictitious skyrmion quasiparticle using fake effective mass and abstract nonphysical math symbol operators (+ adjustable parameters ) with No concrete shapes ( this p.4-5, this p.5 ), which pseudo-models clearly obstruct scientific development.
Half-skyrmion is called meron quasiparticle, which is also a fictional useless particle.
Actually, attempts to utilize this tiny unstable magnetic vortex or skyrmion quasiparticle for some (hyped) practical application such as data storage, memory or transistor are impractical, facing many challenges ( this-abstract-still No skyrmion application, this-lower challenges ahead ).
This p.4-right-1st-paragraph says
"many challenges must be overcome before magnetic
skyrmions can be applied to practical products" ← still No practical use
↑ This skyrmion easily breaks (= unstable ) in room temperature ( this-6th-paragraph ). Furthermore, precise creation and control of elusive skyrmion's magnetic state are impossible, hence useless for devices ( this p.1-right, this p.16(or p.15)-conclusion, p.16(or p.15)-right-upper, this p.1-left-middle ).
This latest paper's p.3-3rd-paragraph (11/7/2024) says
"However, realizing the potential of skyrmion in real applications requires overcoming several
challenging prerequisites including controllable isolated skyrmion generation/deletion, shifting
to a desired position, and reliable detection"
Another latest paper p.1-left-2nd-paragraph also says
"Nevertheless, still substantial challenges remain for memory and logic applications of skyrmions. In particular, ferromagnetic (FM) skyrmions experience transverse deflection
from the motion along the current due to the skyrmion Hall
effect, which may result in their annihilation at the
edge of the racetrack"
This p.1-right-last-paragraph says
"However, because of their random location and
variable character, naturally occurring defects offer little control over the formation of skyrmions and are unsuitable as a
nucleation method for devices (= skyrmion is too unstable and appears in random uncontrollable locations, so impractical for any devices )."
This p.2-left-last-paragraph says
" The positional stability
of skyrmions is a critical issue for both of these applications because a randomly displaced skyrmion can alter
the bit sequence"
This p.2-left-2nd-paragraph says
"Despite the potential for competitive technology, the development of a skyrmion quantum processor will face near-term
challenges. On a fundamental level, these include among others the identification of candidate frustrated magnets with low
damping, the microscopic understanding and control of noise
sources,..
On a device-specific level, the deterministic
and precise skyrmion nucleation, the efficient determination
of the fidelity of quantum operations, and robust and reproducible device fabrication are among the pressing issues to be
addressed."
(Fig.4') Despite longtime researches since 1961, skyrmion quasiparticle is still useless (= hopeless forever ).
The fictitious Skyrmion concept is very old, introduced in 1961.
↑ Despite the extremely long years of researches since 1961, the (fictional) skyrmion quasiparticles are still useless (= nobody around you uses this skyrmion quasiparticle ), which fact proves (overhyped) skyrmion is deadend, hopeless forever.
The 4th paragraph of this (hyped) news (11/21/2024) says
"While practical applications of magnetic skyrmions are likely to be many years off (= fictional skyrmion quasiparticle is still useless despite extremely longtime research, deadend )"
This p.6-Figure 3 shows the theoretical estimation of skyrmion quasiparticle lifetime (= τ ) is extremely short, less than 10-5 seconds at temperature higher than 25K. ← Skyrmion is too unstable and completely useless for data storage or memory.
This p.4-Fig.3 the estimated skyrmion lifetime (= τsk ) is less than 10-9 seconds or nanoseconds at room temperature (= 300K, 1/T = 0.0033 ), which is completely useless, too short-lived to use as memory.
This research paper ↓
p.1-first-paragraph says "however, there is still a long way for putting the skyrmion-based racetrack memory to practice. For example, to create, drive and annihilate/destroy the skyrmions or the skyrmion cluster at will is still a challenge. In particular, current-driven skyrmions will drift from the racetrack direction due to the presence of Magnus force if the velocity is high enough, which leads to their annihilation at the racetrack edge and the loss of information."
p.2-3rd-paragraph says "the skyrmion can stay at the racetrack for only about 1.2ns (= skyrmion is extremely unstable and short-lived ),..
. At t= 1.2ns, the skyrmion touches the upper edge of the racetrack
due to the Magnus force and loses its topological stable skyrmion state, which annihilates eventually within 0.1 ns
so that there is No skyrmion left in the racetrack at t=1.3ns (= skyrmion's lifetime is only nano-seconds, which is impractical )"
p.6-Method~p.7-Table 3 used artificially-chosen parameters and unphysical models (= No particle picture ) with No quantum mechanical prediction for fictional skyrmion quasiparticles.
This other research paper ↓
p.3-left-2nd-paragraph mentions "Our investigation commenced by examining the magnetic hysteresis loop along the c-axis for a 92.6-nm-thick FGaT flake using a polar magneto-optic Kerr effect (MOKE) microscope" ← This Kerr effect or MOKE just measured the change of polarized light reflecting from magnetic material, No electron spin is relevant.
p.5-Figure.4 shows skyrmion lifetime (= τ ) was shorter than 300μs, which is impractical.
The 1-3rd, 9th, last paragraphs of this hyped news say
"Scientists want to replace electrons with so-called 'nanobubbles' — or skyrmions (= fictional quasiparticle ) — to store data more densely and efficiently in advanced components that would replace RAM and flash storage (= overhype, skyrmion quasiparticle is too unstable to replace the practical data storage )."
"A bizarre type of magnetic quasiparticle that looks like a tiny, swirling bubble could one day (= just speculation ) be used as a computing bit in future memory devices."
"A skyrmion generates itself from magnetic field lines as it moves through a medium. The quasiparticle comprises elementary nanomagnets, called spins (= false, electron is Not spinning )"
"Previously, skyrmions had only moved as fast as 100 meters per second (roughly 225 mph), which is too slow to compete with state-of-the-art technologies, the scientists said. But in the study, they sped up skyrmions to speeds of 900 m/s (approximately 2,000 mph). This is an "important step for skyrmion-based devices." ← just moving skyrmion a little faster does Not lead to practical memory device.
"If exploited in future research, skyrmions could (= just speculation ) become the basis of a component that combines the functionality of a central processing unit (CPU)" ← overhype, this research fictional skyrmion has nothing to do with practical use.
↑ This research paper ( this ↓ ).
p.2-top says "This is an important issue for devices because it can cause skyrmions to move toward the track edges where they can be annihilated (= skyrmion is easily destroyed )"
p.4-1st~2nd-paragraphs say "Figure 2C shows an example of a magnetic force microscopy (MFM) image at zero field displaying isolated skyrmions... The skyrmions have different shapes and their size ranges between 100 nm and 700 nm (= controlling skyrmion's size and position is impossible )"
"Using experimental parameters (= No quantum mechanical prediction ), a diameter d = 197 nm is predicted"
p.8-Fig.4 shows skyrmion's lifetime was so short that they could be observed for only nanoseconds (= ns ), which is impractical for data storage device.
p.10 used unreal effective mass m.
p.20 used artificially-chosen parameters with No quantum mechanical prediction
The last paragraph of this overhyped news (10/24/2024)
says
"While much remains to be done before skyrmions can be integrated into ( hopeless ) quantum computing,.. The development of nanoscale metrology, coupled with the ability to control skyrmion dynamics optically, may one day (= just baseless speculation, still useless ) lead to practical skyrmion-based quantum computers and spintronic devices."
The 2nd and 2nd-last paragraphs of this overhyped news (5/22/2025) say
"a discovery that could one day (= just speculation, still useless ) lead to more efficient memory and sensing devices"
"skyrmion... something that could benefit data storage, neuromorphic computing.."
↑ This research paper-p.1-abstract says nothing about any useful technologies like a data storage, memory nor neuromorphic computing.., contrary to the above hyped news.
(Fig.6) ↓ The measured real electrons with real mass were intentionally misinterpreted as fictional massless Dirac or Weyl quasiparticles.
Dirac fermions (or Dirac cone, Dirac semimetal ) and Weyl fermions are all unreal quasiparticles caused by intentionally misinterpreting the measured momentum and energy of electrons ejected by light in the method called ARPES ( this p.4 ).
Majorana fermion is also an imaginary quasiparticle model artificially created to explain some electric conductance (= unreal quasiparticle itself can Not be measured ) and deadend quantum computer.
None of these fictitious quasiparticles have concrete shapes or size, hence, obstructing the real science, which dire facts must be covered up by overhyped news.
The 2nd-3rd, 6th, last paragraphs of this hyped news say
"The mysterious Weyl fermions were, in fact, detected for the first time in 2015; they turned out Not to be free particles like the neutrino, which can move through the universe independently from the rest of the world, but rather '(fictional) quasiparticles' in a solid state."
"Quasiparticles are Not particles in the conventional sense, but rather excitations of a system consisting of many interacting particles"
"According to the laws of relativity, free massless particles must always spread at light speed. This is, however, not the case in solid states: "Even though our Weyl fermions have no mass, their speed is extremely low (= quantum mechanical fictional Weyl quasiparticle contradicts relativity )"
"The Weyl fermions are only dispersed in the material to a minimal extent, meaning they can conduct electrical current almost without loss (= false, No evidence of lossless current ) -- this is of great significance for electronics. They are also likely to be extremely interesting to the field of spintronics,.. Weyl fermions will (= just speculation ) be of interest here due to their particularly robust spin. The particle should also be especially well suited for use in (deadend) quantum computers." ← Overhype, this fictional Weyl quasiparticle has No practical use.
The last paragraph of this recent website on fictional Dirac and Weyl quasiparticles just vaguely says
"The discovery could lead to practical applications in the future (= still unrealized ). “While it’s still early days, this finding could pave the way toward realizing next-generation electronic devices that utilize new fermions,.. They may (= just speculation ) be useful for high-speed devices"
↑ No practical use of these quasiparticles, and only hyped news is rampant.

p.1-left-last~p.1-right-1st-paragraph says "Here, we report the first direct observation of massless Dirac fermions coexisting with quasiparticles with finite effective mass in graphite, by using angle-resolved photoemission spectroscopy (ARPES)."
↑ This ARPES can just detect real electrons (= e- ) with real mass, which was intentionally misinterpreted as fictional Dirac quasiparticle with fake effective mass due to wrong assumption and free parameters.
p.2-right mentions "quasiparticles that have finite (fictional) effective mass"
Another recent research paper on fictional Dirac quasiparticle ↓
p.1-abstract-last says "Our findings establish the general optical response of massive Dirac fermions (= fictional quasiparticle ), which is closely related to the universal electrodynamics in quantum anomalous Hall state (= No mention of practical use )"
p.1-left says "It has recently been recognized that the nonlinear optical effect and magnetooptical (MO) effect are enhanced in topological materials.."
"When the Fermi level is controlled in between the mass gap, the anomalous Hall response shows the quantized conductance e2 /h, establishing the quantum anomalous Hall (QAH) state" ← Measurement of classical polarized light (= Kerr magnetooptical efect ) and Hall effect based on classical Lorentz magnetic force were used to (falsely) estimate the existence of fictional Dirac quasiparticle.
p.6-right used one-pseudo-electron DFT with full relativistic projector augmented-wave (PAW) pseudopotentials (= artificially chosen, so No quantum mechanical prediction ), and saying "the spin-polarized DFT often overestimates the magnetic exchange splitting"
↑ The current mainstream one-pseudo-electron DFT is useless, wrong, unable to predict any values.
The 4th, 7th, 9th paragraphs of this hyped news say
4th
"Now, a group headed by Zahid Hasan at Princeton University has found evidence that Weyl fermions exist as (fictional) quasiparticles – collective excitations of electrons – in the semimetal tantalum arsenide (TaAs)"
"... This means that TaAs should have Weyl fermions in its bulk and a distinct feature on its surface called a "Fermi arc (= some fictional electron's energy and momentum relation )". Using a standard technique called angle-resolved photoemission spectroscopy (ARPES), the team found evidence of a Fermi arc." ← ARPES can just detect real electrons, Not fictional (Weyl or Dirac) quasiparticles.
7th
"The team fired microwaves at the crystal and measured microwave transmission through the crystal while changing its orientation to the incident microwave beam – and varying the frequency of the microwaves. This allowed the researchers to map out the photonic band structure of the crystal, which reveals which microwave frequencies can travel through the crystal and which cannot. This revealed the presence of “Weyl points” in the band structure, which are indicative of Weyl fermion states"
↑ They just measured (classical) microwave (= Not Weyl quasiparticle itself ) changed by some material, and (mis)interpreted it as fictional Weyl fermion quasiparticle.
9th
"Weyl fermions could (= just speculation ) be very useful because their massless nature would allow them to conduct electric charge through a material much faster than normal electrons (= false, massless is fake effective mass, Not real ) – which could be used to create faster electronic circuits. This property is also shared by electrons in graphene. However, unlike graphene, which is a 2D material, Weyl fermions should exist in more practical 3D materials. Furthermore, Weyl particles are topologically protected (= No evidence of topological protection ) from scattering, which means that they could be useful in quantum computers (= hype, quantum computer is already deadend )."
↑ This research paper's abstract last just vaguely says "Our work opens the field for the experimental study of Weyl fermions in physics and materials science. " ← No mention of detailed practical application, so Weyl fermion quasiparticle is just unreal and useless, contrary to hypes (= topologically-protected or something ).
↑ this supplementary material ↓
p.2-1st-paragraph says "The experimental geometry of SX-ARPES has been described in (29). The sample was cooled down to 12K (= too low temperature to be practical )"
p.2-last-paragraph used one-pseudo-electron DFT with artificially-chosen pseudo-potentials. ← No quantum mechanical prediction.
As a result, it is impossible to put such fictional quasiparticle models to practical use, so academia and the media desperately try to hide this deadend quantum mechanical model by spreading overhyped news with misleadingly colorful particle pictures now.
The 1st and 2nd paragraphs of this overhyped news (1/11/2025) says
