BCS-BEC crossover with a finite-range interaction
Meera M. Parish, Bogdan Mihaila, Eddy M. Timmermans +2
We study the crossover from BEC to BCS pairing for dilute systems but with a realistic finite-range interaction. We exhibit the changes in the excitation spectrum that provide a cl…
Fermion-mediated BCS-BEC Crossover in Ultracold Potassium-40 Gases
M. M. Parish, B. Mihaila, B. D. Simons +1
Studies of Feshbach resonance phenomena in fermionic alkali gases have drawn heavily on the intuition afforded by a Fermi-Bose theory which presents the Feshbach molecule as a feat…
Renormalizing the Schwinger-Dyson equations in the auxiliary field formulation of field theory
Fred Cooper, Bogdan Mihaila, John F. Dawson
In this paper we study the renormalization of the Schwinger-Dyson equations that arise in the auxiliary field formulation of the O(N) field theory. The auxiliary field formul…
