The integer quantum Hall effect (QHE) in a 2D electron system (2DES) under a perpendicular magnetic field is the first example of a topological quantum state 1,2,3,4,5.In the QHE, the Hall ... 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 ...

these states can be found. The Fractional Quantum Hall (FQH) Effect, or the emergence of Hall Resistances quan-tized in fractional multiples of flux quantum, requires us to treat the interactions between electrons, which is tractable in this paper for a few simple cases.

A model of the non-Abelian fractional quantum Hall effect is obtained from the diagonalization of the matrix model proposed by Dorey, Tong, and Turner (DTT). The Hamiltonian is reminiscent of a spin Calogero-Moser model but involves higher-order symmetric representations of the non-Abelian symmetry. We derive the energy spectrum …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. Because the current is carried only by the states at the center of each Landau level, the current should jump discontinuously as the Fermi level is tuned ...Lectures on the Quantum Hall Effect.
