Pairing in two-dimensional boson-fermion mixtures

Jordi Mur-Petit, A. Polls, M. Baldo, H.-J. Schulze

Abstract

The possibilities of pairing in two-dimensional boson-fermion mixtures are carefully analyzed. It is shown that the boson-induced attraction between two identical fermions dominates the p wave pairing at low density. For a given fermion density, the pairing gap becomes maximal at a certain optimal boson concentration. The conditions for observing pairing in current experiments are discussed.
