Tan contact and universal high momentum behavior of the fermion propagator in the BCS-BEC crossover
Igor Boettcher, Sebastian Diehl, Jan M. Pawlowski +1
We derive the universal high momentum factorization of the fermion self-energy in the BCS-BEC crossover of ultracold atoms using nonperturbative quantum field theoretical methods.…

Ultracold atoms and the Functional Renormalization Group
Igor Boettcher, Jan M. Pawlowski, Sebastian Diehl
We give a self-contained introduction to the physics of ultracold atoms using functional integral techniques. Based on a consideration of the relevant length scales, we derive the…
