Abstract

We identify a non-Fermi-liquid class of fixed points describing the infrared behavior of interacting chiral fermions in one dimension. The thermodynamic properties and asymptotic correlation functions are characterized by universal exponents, which we determine by means of conformal and Bethe Ansatz techniques. The mechanism leading to the breakdown of Fermi-liquid theory is quite general and can be expected to be realized in systems with broken T invariance. As an example we study the edge states of interacting quantum Hall effect systems, where we calculate the universal NMR response.
