Finite-Temperature Behavior of an Inter-species Fermionic Superfluid with Population Imbalance
Hao Guo, Chih-Chun Chien, Qijin Chen +2
We determine the superfluid transition temperature and related finite temperature phase diagrams for the entire BCS-Bose Einstein condensation crossover in a homogeneous mixt…
Comparison of Different Pairing Fluctuation Approaches to BCS-BEC Crossover
K. Levin, Qijin Chen, Chih-Chun Chien +1
The subject of BCS - Bose Einstein condensation (BEC) crossover is particularly exciting because of its realization in ultracold Fermi gases and its possible relevance to high temp…
Fermions with attractive interactions on optical lattices and implications for correlated systems
Chih-Chun Chien, Qijin Chen, K. Levin
In this paper we address the behavior of the superfluid transition temperature in the attractive Hubbard model. We study systematically the effects of pairing fluctuations an…
Superfuid-insulator transitions at non-integer filling in optical lattices of fermionic atoms
Chih-Chun Chien, Yan He, Qijin Chen +1
We determine the superfluid transition temperatures and the ground states of the attractive Hubbard model and find new insulating phases associated with non-integer filling a…
Heat Capacity of a Strongly-Interacting Fermi Gas
J. Kinast, A. Turlapov, J. E. Thomas +3
We have measured the heat capacity of an optically-trapped, strongly-interacting Fermi gas of atoms. A precise input of energy to the gas is followed by single-parameter thermometr…
Heat Capacity of a Strongly-Interacting Fermi Gas
J. Kinast, A. Turlapov, J. E. Thomas
We report on the measurement of the heat capacity for an optically-trapped, strongly-interacting Fermi gas of atoms. In the experiments, a precise input of energy to the gas is fol…
