Hall effect: Do the charges that build up on the sides of conductor kept in uniform magnetic field get uniformly distributed?
When we keep a metal block through which some constant current is flowing in a uniform magnetic field the charges will separate and a potential difference will be created b/w the sides of the ...

Longitudinal conductivity from density of states (DOS)
It is well-known that using the so-called Streda formula, the transversal conductivity $\sigma_{xy}$ and thus the Hall conductivity in a two-dimensional material is given as the derivative of the ...

Computing a second harmonic resistance out of a wave-like resistance signal
I want to reproduce the results of a paper, in which they measure the Anharmonic Hall Effect (AHE) resistance $R_{AHE}^{2\omega}$. There are several protocols for measuring it experimentally, but I'm ...

Relationship between the magnetic dipole of the electron and the polarisation of its radiation
When passing through a magnetic field, electrons are deflected sideways. This is the basis of the Lorentz force and all Hall effects. If this is done on a larger scale in particle accelerators or, in ...

How to calculate the total charge separated by the Hall effect?
If a plate is undergoing the Hall Effect, how can we calculate the total charge $Q$ present on either side of the plate at the equilibrium state?
And how can we calculate the force that such a charge ...

Why (intuitively) do more charge carriers result in a smaller Hall effect?
From the equation for the Hall effect:
$$\Delta V_H= \frac{I B}{n q t}$$
[Where $I$ is the current, $B$ the electric field magnitude, $n$ the density of charge carriers, $q$ the charge per charge ...

Does the Hall effect increase the resistance of a wire?
If a current in a wire is flowing perpendicular to a magnetic field, the Hall effect is observed. This effect is caused by the forces from magnetic fields pushing the electrons to one side of the wire....
