qhe. 5. Chern-Simons Theories. So far we’ve approached the quantum Hall states from a microscopic perspective, look-ing at the wavefunctions which describe individual electrons. In this section, we take a step back and describe the quantum Hall e↵ect on a more coarse-grained level. Our goal is to construct e↵ective field theories which ...
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.David Tong's 129 research works with 8,293 citations and 4,053 reads, including: ...

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 …Dec 15, 2015 · Abstract. We 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. We quantize the vortices and, by relating their dynamics to a matrix model, show that their ground state wave function is in the same universality class ...

This doubling indeed happens in the "quantum spin Hall effect", but those systems are at zero magnetic field (and moreover enjoy time reversal symmetry, which is key). However, in the usual quantum Hall effect, there is a huge static magnetic field, which polarizes all the low energy electrons (the Zeeman splitting is large because it goes like ...
