F-electron spectral function near a quantum critical point

arXiv:cond-mat/0407412 · doi:10.1016/j.physb.2005.01.192

Abstract

We calculate the f-electron spectral function using a Keldysh formalism for the Falicov-Kimball model in infinite dimensions. We study the region close to the quantum critical point on both the hypercubic and Bethe lattices.
