When he tweaked the variables in the fluid flow equations, he found that those equations were equivalent to Maxwell-Chern-Simons theory, which describes how electrons move in a magnetic field.

The original, classical Hall effect was discovered in 1879 by Edwin Hall. It is a simple consequence of the motion of charged particles in a magnetic field. The setup for the same is as follows, consider a rectangular bar with thickness, t, Length L, and width W, as shown in Fig 1. Now a constant current along the x axis is passed.David Tong: Lectures on Solid State Physics. This is an introduction to solid state physics.

The Integer Quantum Hall (IQH) Effect shows that this resistivity is quantized to extraordinary precision in inte-ger multiples of fundamental flux when the conductor is brought to very low temperatures.

From the simple picture that extended states form only at the center of each Landau level and all the other states are localized, we can explain the origin of the Quantum hall plateaux.

It implies that many electrons, acting in concert, can create new particles having a chargesmallerthan the charge of any indi- vidual electron. This is not the way things are supposed to be. manti courthouse An Introduction to the Quantum Hall Effect. The Quantum Hall Effect is a fascinating phenomenon that occurs in two-dimensional electron systems subjected to low temperatures and strong magnetic fields.
