Description
We calculate the effect of infrared fluctuations of the Chern-Simons gauge field on the single-particle Green close-quote 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. copyright 1997 The American Physical Society
