Research output: Contribution to journalArticle


We investigate fermion liquids interacting with longitudinal and transverse Abelian gauge fields via bosonization. In two spatial dimensions we obtain the fermion quasiparticle propagator for the specific case of a Coulomb plus Chern-Simons gauge action. In the Halperin-Lee-Read theory of the half-filled Landau level this action describes composite fermions moving in zero net magnetic field. We identify the novel non-Fermi-liquid fixed point which controls the low-energy ν=1/2 physics and show how Kohn's theorem is satisfied.
