Understanding the superfluid phase diagram in trapped Fermi gases
Qijin Chen, C. A. Regal, M. Greiner +2
Trapped ultracold Fermi gases provide a system that can be tuned between the BCS and BEC regimes by means of a magnetic-field Feshbach resonance. Condensation of fermionic atom pai…
Ground State Description of a Single Vortex in an Atomic Fermi gas: From BCS to Bose-Einstein Condensation
Chih-Chun Chien, Yan He, Qijin Chen +1
We use a Bogoliubov-de Gennes (BdG) formulation to describe a single vortex in a neutral fermionic gas. It is presumed that the attractive pairing interaction can be arbitrarily tu…
Applying BCS-BEC Crossover Theory To High Temperature Superconductors and Ultracold Atomic Fermi Gases
Qijin Chen, Jelena Stajic, K. Levin
This review is written at the time of the twentieth anniversary of the discovery of high temperature superconductors, which, nearly coincides with the important discovery of the su…
Population of closed-channel molecules in trapped Fermi gases with broad Feshbach resonances
Qijin Chen, K. Levin
We compute the fraction of closed-channel molecules in trapped atomic Fermi gases, over the entire range of accessible fields and temperatures. We use a two-channel model of BCS--B…
Radio frequency spectroscopy and the pairing gap in trapped Fermi gases
Yan He, Qijin Chen, K. Levin
We present a theoretical interpretation of radio-frequency (RF) pairing gap experiments in trapped atomic Fermi gases, over the entire range of the BCS-BEC crossover, for temperatu…
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…
