Thermodynamics and superfluid density in BCS-BEC crossover with and without population imbalance
Yan He, Chih-Chun Chien, Qijin Chen +1
We address the thermodynamics, density profiles and superfluid density of trapped fermions undergoing BCS-BEC crossover, with and without population imbalance. Our approach represe…
Radio Frequency Spectroscopy of Trapped Fermi Gases with Population Imbalance
Yan He, Chih-Chun Chien, Qijin Chen +1
Motivated by recent experiments, we address, in a fully self consistent fashion, the behavior and evolution of radio frequency (RF) spectra as temperature and polarization are vari…
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…
First and second sound modes at finite temperature in trapped Fermi gases from BCS to BEC
Yan He, Qijin Chen, Chih-Chun Chien +1
We determine the temperature dependence of first and second sound mode frequencies for trapped Fermi gases undergoing BCS to Bose Einstein condensation (BEC) crossover. Our res…
Fermionic superfluidity: From high Tc superconductors to ultracold Fermi gases
Qijin Chen, Chih-Chun Chien, Yan He +1
We present a pairing fluctuation theory which self-consistently incorporates finite momentum pair excitations in the context of BCS--Bose-Einstein condensation (BEC) crossover, and…
