Classical and quantum Hall effects
I am trying to understand the hall effects and have a few problems with them.
So let's consider the classical Hall effect. We know that we consider a sample, where the electrons flow, we apply the ...

Quantum Hall effect diverges at $B=0$
In the integer quantum Hall effect, with the applied magnetic field reduced, more and more LLs get filled and one can observe higher and higher plateaus in the Hall conductivity $\sigma_H(B)$. ...

Shubnikov-de-Haas effect and Quantum Hall effect
I am wondering if these two phenomena are two names for the same thing or whether these are distinct effects and there are situation where one appears, but the other one doesn't?
Both seem to produce ...

Why are the plateaus in the Quantum Hall horizontal rather than diagonal
I was wondering why the plateaus of $\rho_{xy}$ in the integer quantum Hall effect are horizontal and do not scale linearly with the magnetic field $B$ since the Lorentz force should still be acting ...

Do I correctly understand the reason why the Hall resistivity in Quantum Hall Effect becomes larger as magnetic field increases?
I'm wondering whether I correctly understand the increase of the Hall resistivity rho_xy in Quantum Hall effect.
As you can see the graph,
As magnetic field becomes much larger, the quantization of ...

Deriving classical Hall effect from quantum Hall effect
I'm interested in the derivation of the classical Hall effect coefficient, given in cgs by $$R_{H}=-\frac{1}{nec},$$ where $n$ is the electron number density, $-e<0$ is the electron charge,and $c$ ...
