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…
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…
Superfluid phase diagrams of trapped Fermi gases with population imbalance
Chih-Chun Chien, Qijin Chen, Yan He +1
We present phase diagrams for population imbalanced, trapped Fermi superfluids near unitarity. In addition to providing quantitative values for the superfluid transition temperatur…
Single-plane-wave Larkin-Ovchinnikov-Fulde-Ferrell state in BCS--Bose-Einstein condensation crossover
Yan He, Chih-Chun Chien, Qijin Chen +1
We study the single-plane-wave Larkin-Ovchinnikov-Fulde-Ferrell (LOFF) states for BCS--Bose-Einstein condensation (BEC) crossover at general temperatures . Because we include th…
Theory of Superfluids with Population Imbalance: Finite Temperature and BCS-BEC Crossover Effects
Qijin Chen, Yan He, Chih-Chun Chien +1
In this paper we present a very general theoretical framework for addressing fermionic superfluids over the entire range of BCS to Bose Einstein condensation (BEC) crossover in the…
