*(Fig.1) Spin-orbit interaction really happens in semiconductor ?*

Electron spin in solids (= spintronics ? ) often becomes Nobel prize candidate as a form of "spin-Hall" and "topological insulator".

But electron spin is physically **impossible**. A tiny point-like electron must rotate at far faster-than-light speed to generate its angular momentum !

Then why does Nobel committee try to give their prestigious prize to **unrealistic** spin ? In other words, **without** Nobel prize, spintronics is
useless.

*(Fig.2) We must use experimental data to predict "real concept" !*

In the present quantum mechanics, even when we get some new experimental **data**, we **cannot** use them to clarify real mechanisms !

Instead, quantum mechanics forces us to use these data to create **artificial** quasiparticle, effective mass .. So our science stops its progress.

This is a very *serious* problem. We must address it immediately not to increase more educational victims under **false** science.

*(Fig.3) Choosing convenient wavefunction from infinte choices is nonsense*

Schrodinger equation cannot be solved in multi-electron atoms except for one-electron hydrogen atom.

So all physicists can do is choose approximate trial function. The problem is there is **NO** restriction in choosing this trial function as candidate.

We can **choose** convenient form of trial wavefunction out of **infinite** choices. So it's impossible to compare infinite possible trial functions giving the lowest energy.

This is the reason why Schrodinger equation is useless, has **NO** power to predict physical values forever, also in DFT and Nobel prize.

*(Fig.4) ↓ Fake mass, fake spin g-factor, fake spin-orbit = semiconductor*

Schrodinger equation in quantum mechanics **cannot** solve *multi*-electrons, so they just choose fake trial wavefunction. It means **useless**.

In solid-physics, they adopt band theory
where they *replace* complicated actual solid electrons by a free single particle with a **unreal** mass ( this p.13 ).

Of course, this band theory is a **false** approximation. It relies on **unreal** effective mass, which can be smaller than the actual electron mass or negative ( this p.5 )

Spin g-factor and spin-orbit coupling are all **unreal** (= called "effective", see this p.8 ) in semiconductor by quantum mechanics.

*(Fig.5) Effective mass in GaAs = 0.0665 m _{0} (= electron mass ) !*

Gallium arsenide (= GaAs ) is a compound semiconductor, which is used as research topic more frequently than any other semiconductors.

Quantum mechanics cannot handle multi-electron atoms and solids. So all physicistis can do is adopt a **fake** free particle with **unreal** mass and spin g-factor !

This "fake mass" is called "effective mass (= m^{*} )", which can be **smaller** and larger than the actual electron mass (= m_{0} ).

For example, effective mass inside GaAs is smaller (= 0.066 m_{0} this p.13 ) than the actual electron mass.

The actual electron spin g factor must be "2", but effective g-factor is less than that ( g^{*} = -0.44, see this p.43 ).

So quantum mechanics depends on **unreal** concepts, which means "useless" !

*(Fig.6) Electric → magnetic in rest frame of moving electron spin ?*

Spin-orbit interaction is thought to be one of Einstein relativistic effect ( this p.7 ), though **faster**-than-light spin itself violates relativity.

Einstein said when an electron (= spin S ) is moving in the electric field (= ∇V), it **feels** the magnetic field (= B ) in its rest frame.

Using Lorentz transformation of electromagnetic fields, we can get the strength of spin-orbit coupling (= λ = -3.7 × 10^{-6} ), which is very **week**.

*(Fig.7) Effective spin-orbit coupling is far bigger than Einstein relativity !*

Though they claim spin-orbit interaction proves Einstein relativistic effect, physicsits adopts fake spin-orbit effect completely **different** from relativity !

They often use "kp approximation" in semiconductors which relies on **unreal** effective spin-orbit equation ( this p.8, this p.3 ).

In this **fake** theory, spin-orbit interaction in GaAs is by six orders of magitude **stronger** than in Einstein theory and has the *opposite* sign ( this p.6, this p.2 )

So when you see "spin-orbit in solids" in various websites, it means **neither** actual spin **nor** Einstein relativity !

These false parameters are artificially **adjusted** to fit experimets, so useless ( this p.2, this p.7 ).

*(Fig.8) Effective mass, g-factor, spin-orbit are unreal.*

Schrodinger equation in quantum mechanics cannot handle multi-electron atoms and molecules, because this theory was invented in **ancient** times (= 1920s ).

So for useless quantum mechanics to treat solids and semiconductors, it has to rely on **unreal** concepts such as *effective* mass, spin-orbit and quasiparticle.

As long as Nobel prize keeps awarded to **unreal** concepts, this prize keeps contributing to **destroy**ing young strudents' career as a convenient tool of scientific fraud !
