Competing instabilities of a Dipolar Fermi Gas
ORAL
Abstract
Recent experiments in the cold atom Fermi gas have explicitly shown the deformation of the Fermi surface in the presence of long range dipolar interactions. Motivated by this, we investigate the competing instabilities of a dipolar Fermi gas within the functional renormalization group. We analyze the flow of the effective action in the particle-particle as well as particle-hole channel, consider the self energy term, and discuss the interplay of different instabilities at low temperatures.
