Abstract

We study a system of fermions interacting with a gauge field which can be used to describe either a spin liquid or the ν=1/2 quantum Hall state. We propose a generalized model with a dimensionless parameter N. We evaluate the properties of the model in both limits N1 and N1 and deduce the properties of the model in the most physically interesting case of N=1,2. At N1 the motion of the fermions becomes one dimensional. By applying the bosonization method in this limit, we obtain the fermion Green function and response functions.
