Three-body scattering from nonperturbative flow equations
S. Diehl, H. C. Krahl, M. Scherer
We consider fermion-dimer scattering in the presence of a large positive scattering length in the frame of functional renormalization group equations. A flow equation for the momen…

Renormalisation Flow and Universality for Ultracold Fermionic Atoms
S. Diehl, H. Gies, J. M. Pawlowski +1
A functional renormalisation group study for the BEC-BCS crossover for ultracold gases of fermionic atoms is presented. We discuss the fixed point which is at the origin of univers…

Universality in the BCS - BEC Crossover in Cold Fermion Gases
S. Diehl
We address the finite temperature phase diagram of ultracold fermionic atoms across a Feshbach resonance based on a functional integral for an atom-molecule model. This allows to f…
