A Framework for Studying a Quantum Critical Metal in the Limit N_f -> 0

Speaker : Petter Säterskog (Leiden U.)
Abstract : We study a toy model in 1+2 dimensions composed of a spherical Fermi surface of N_f flavours of fermions coupled to a massless scalar. We present a framework to non-perturbatively calculate general real space fermion n-point functions of this theory to leading order in the limit N_f -> 0 followed by k_F -> \infty where k_F sets both the size and curvature of the Fermi surface. Using this framework we calculate the fermion two-point function and the fermion density-density correlation function. We comment on the effects of N_f corrections.
