Abstract. Two-dimensional electron systems in a high magnetic field behave very strangely. They exhibit rational fractional quantum numbers and contain exactly fractionally charged particles. Electrons seem to absorb magnetic flux quanta, altering their statistics and consuming the magnetic field. They condense into a manifold of novel …David Tong: Concepts in Theoretical Physics.

Mainly, I was trying to understand the quantized hall resistivity in terms of the number of Landau levels crossing the fermi energy. Then, I began thinking about why spin induced Zeeman splitting is never really mentioned in the context of IQHE.

3. The Fractional Quantum Hall E↵ect We’ve come to a pretty good understanding of the integer quantum Hall e↵ect and the reasons behind it’s robustness. Indeed, some of the topological arguments in the previous chapter are so compelling that you might think the Hall resistivity of an insulator has to be an integer.

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.As the charge Hall current can be more easily measured in experiments, the anomalous valley Hall effect offers a possible way to realize data storage utilizing ferrovalley materials.
