David tong quantum hall effect.

We investigate numerically the integer quantum Hall effect (IQHE) in a two-dimensional square lattice with non-interacting electrons subjected to disorder and uniform magnetic field in a direction perpendicular to the lattice plane.

David tong quantum hall effect. Things To Know About David tong quantum hall effect.

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. Yang-Mills instantons are solitonic particles in d = 4 + 1 dimensional gauge theories. We construct and analyse the quantum Hall states that arise when these particles are restricted to the lowest Landau level.
