Thermodynamics of a Trapped Unitary Fermi Gas
Aurel Bulgac, Joaquin E. Drut, Piotr Magierski
We present the first model-independent comparison of recent measurements of the entropy and of the critical temperature of a unitary Fermi gas, performed by Luo et al., with the mo…
Comment on "Structure of a Quantized Vortex near the BCS-BEC Crossover in an Atomic Fermi Gas"
Aurel Bulgac
A comment on the letter by M. Machida and T. Koyama, Phys. Rev. Lett. {\bf 94}, 140401 (2005) and also on the preprint by Y. Kawaguchi and T. Ohmi, cond-mat/0411018.
Molecular transitions in Fermi condensates
Aurel Bulgac, George F. Bertsch
We discuss the transition of fermion systems to a condensate of Bose dimers, when the interaction is varied by use of a Feshbach resonance. We argue that there is an intermediate p…
The spatial profile of the matter distribution in a dilute atomic-molecular Fermi cloud
Aurel Bulgac
A dilute atomic-molecular fermion in a trap acquires a rather complex layered spatial structure. At very low temperatures, typically at the center of the trap, a superfluid bosonic…
A dilute atomic Fermi system with a large positive scattering length
Aurel Bulgac, Paulo F. Bedaque, Antonio C. Fonseca
We show that a dilute atomic Fermi system at sufficiently low temperatures, can display fermionic superfluidity, even in the case of a repulsive atom-atom interaction, when the sca…
Atomic-Molecular Condensates with Large Positive Scattering Length
Aurel Bulgac, Paulo F. Bedaque
We show that in the limit of large and positive atom--atom scattering length the properties of an atomic--molecular Bose--Einstein Condensate (amBEC) are determined by an universal…
