Abstract

Ultracold atom systems and the high Tc superconductors provide us with examples of systems where BCS-BEC crossovers and quantum phase transitions could potentially be explored. In this talk I will focus on the Fermi surface (or the underlying Fermi surface) in these systems, and discuss how this could be affected by proximity to the BCS-BEC crossover or to quantum phase transitions in the context of specific models. I will also summarize other results from our recent work on the crossover in a 2D honeycomb lattice.
