摘要：

We calculate the effect of infrared fluctuations of the Chem-Simons gauge field on the single particle Green's function of composite fermions in the half-filled Landau level via higher-dimensional bosonization on a curved Fermi surface. We find that composite fermions remain well-defined quasiparticles, with an effective mass given by the mean-field value, but with anomalously large damping and a spectral function that contains considerable weight away from the quasiparticle peak.
