1.3 The Classical Hall E ect Let us rst look at the classical Hall e ect and then see how it di ers from the quantum Hall e ect. The classical Hall e ect was discovered by Edwin Hall in 1879. The set-up is as follows: Electrons are restricted to move in the 2D (x,y)-plane while a constant magnetic eld points in the z-direction.

The quantum Hall effect is a prototypical realization of a topological state of matter. It emerges from a subtle interplay between topology, interactions and disorder 1,2,3,4,5,6,7,8,9.
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. A satisfactory model of IQH states emerges from a non-interacting model of the electrons in the conductor and a band structure of these states ...

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.
