Edge waves in the quantum Hall effect

I show that the bosonized form of the low energy edge excitations at the surface of a droplet of two-dimensional quantum Hall liquid can be understood in terms of coherent “ripplon” deformations in the shape of the droplet. When interacting with an electromagnetic field the resulting chiral boson theory has anomalies that are cancelled, via the Callan-Harvey mechanism, by contributions from the bulk. I also consider non-Abelian generalization of the bosonization that may be useful for chiral spin states.

Supersymmetric chiral bosons

We present the (1, 0) supersymmetric chiral boson theories. Actions, including the coupling to abelian gauge superfields, and chiral super-currents are written down for self-dual bosons. The condition for proper BRST quantization are discussed. The “reparametrization anomalies” are removed by the stringy prescription of considering multiplets of superfields and by the introduction of a Liouville term. The Siegel super-ghost system is super-bosonized. An anomaly free action which couples chiral bosons to supergravity, is proposed.
