David tong quantum hall effect.

1. In David Tong's notes on the quantum hall effect, when calculating the current due to edge modes, he writes it's expression as. Iy = −e ∫ dk 2πvy(k) I y = − e ∫ d k 2 π v y ( k) where vy v y is the drift velocity of the state with momentum ℏk ℏ k. But I fail to understand how that gives the current. The purpose of these lectures is to describe the basic theoretical structures underlying the rich and beautiful physics of the quantum Hall effect. The focus is on the interplay between microscopic wavefunctions, long-distance effective Chern-Simons theories, and the modes which live on the boundary. The notes are aimed at graduate students in ... Quantum Hall effects in graphene 55, 56 have been studied intensively. Generally speaking, the IQHE in graphene has the same underlying mechanism as that in the semiconductor 2DEG. Readers are referred to Chapter 4 for the basic concepts of quantum Hall effects in semiconductors, e.g. Landau levels, cyclotron frequency, degeneracy …The experimental data for the Hall resistivity shows a number of plateaux labelled by an integer ⌫.Meanwhile,theenergyspectrumforms Landau levels, also labelled by an integer. Each Landau level can accommodate a large, but finite number of electrons. E k n=1 n=2 n=3 n=4 n=5 n=0 Figure 12: Integer quantum Hall e↵ect Figure 13: Landau levelsWe introduce a supersymmetric Chern-Simons theory whose low energy physics is that of the fractional quantum Hall effect. The supersymmetry allows us to solve the theory analytically.

This non-linear Hall effect has a quantum origin: it is related to the geometric properties of the electronic wavefunctions and encoded in the dipole moment of the Berry curvature. Here, the general theory underpinning this effect is reviewed and various material platforms where non-linear Hall transverse responses have been found are discussed.
