The frustrated FCC antiferromagnet Ba2YOsO6: structural characterization, magnetic properties and neutron scattering studies

E. Kermarrec, C. A. Marjerrison, C. M. Thompson +8

We report the crystal structure, magnetization and neutron scattering measurements on the double perovskite BaYOsO. The space group is found both at 290~K…

Probing the Spectral Function Using Momentum Resolved Radio Frequency Spectroscopy in Trapped Fermi Gases

Qijin Chen, K. Levin

We address recent momentum resolved radio frequency (RF) experiments on ultracold trapped Fermi gases of K. We show that momentum resolved RF probes provide measurements of…

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…

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…

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…
