(Fig.1) Quantum mechanical atomic model lacks reality.
The 1st, 7th paragraphs of this hyped news (8/16/2025) say
"Researchers.. have discovered direct evidence of active flat electronic bands in a kagome superconductor. This breakthrough could pave the way for new methods to design quantum materials—including superconductors, topological insulators and spin-based electronics—that could power future electronics and computing technologies" ← fake news
"They used angle-resolved photoemission spectroscopy (ARPES) to map electrons emitted under synchrotron light, revealing distinct signatures associated with compact molecular orbitals. Resonant inelastic X-ray scattering (RIXS) measured magnetic excitations linked to these electronic modes."
↑ Quantum mechanics is useless, able to express materials only as fictional quasiparticle model with fake effective mass in unphysical band model that is useless for any technologies such as computer transistors, contrary to hypes.
Flat band means unreal infinite (effective) mass ( this-1st-paragraph ) of the fictional quasiparticle model ( this-1st, 3rd-paragraphs ).
This-1st-paragraph says
"The idea of flat-band electronic structures has roots in theoretical models from decades past.... creating effectively "infinitely heavy (= unreal )" electrons"
↑ This research paper ↓
p.1-abstract says nothing about any practical use such as computers (= because infinite mass flat band is unreal ), contrary to the above overhyped fake news.
p.1-right-last mentions Dirac fermion that is also a fictional quasiparticle with fake mass.
p.2~7 showed No real particle picture.
p.8 used one pseudo-electron DFT model based on artificially-chosen pseudo-potential that is useless, unable to predict anything including unreal quasiparticles and fictional spin.
↑ So this research just measured electrons (= ARPES ) and X-ray scattered by some superconductors, and imagined the fictional infinite-mass quasiparticle in the unphysical flat band model with No practical application such as the hyped computers.
