Thermodynamics of Interacting Fermions in Atomic Traps
Qijin Chen, Jelena Stajic, K. Levin
We calculate the entropy in a trapped, resonantly interacting Fermi gas as a function of temperature for a wide range of magnetic fields between the BCS and Bose-Einstein condensat…
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…
Density Profiles of Strongly Interacting Trapped Fermi Gases
Jelena Stajic, Qijin Chen, Kathryn Levin
We study density profiles in trapped fermionic gases, near Feshbach resonances, at all and in the near-BEC and unitary regimes. For the latter, we quantify and charact…
BCS-BEC Crossover: From High Temperature Superconductors to Ultracold Superfluids
Qijin Chen, Jelena Stajic, Shina Tan +1
We review the BCS to Bose Einstein condensation (BEC) crossover scenario which is based on the well known crossover generalization of the BCS ground state wavefunction . While…
Particle Density Distributions in Fermi Gas Superfluids: Molecular Boson Effects
Jelena Stajic, Qijin Chen, K. Levin
We show how to describe the behavior associated with the usual BCS- Bose Einstein condensation (BEC) crossover ground state. We confine our attention here to the BEC and…
