Probing the critical exponent of superfluid fraction in a strongly interacting Fermi gas
Hui Hu, Xia-Ji Liu
We theoretically investigate the critical behavior of second sound mode in a harmonically trapped ultracold atomic Fermi gas with resonant interactions. Near the superfluid phase t…
Fulde-Ferrell pairing instability of a Rashba spin-orbit coupled Fermi gas
Xia-Ji Liu
We theoretically analyze the pairing instability of a three-dimensional ultracold atomic Fermi gas towards a Fulde-Ferrell superfluid, in the presence of Rashba spin-orbit coupling…
Topological Fulde-Ferrell superfluid in spin-orbit coupled atomic Fermi gases
Xia-Ji Liu, Hui Hu
We theoretically predict a new topological matter - topological inhomogeneous Fulde-Ferrell superfluid - in one-dimensional atomic Fermi gases with equal Rashba and Dresselhaus spi…
Fulde-Ferrell superfluidity in ultracold Fermi gases with Rashba spin-orbit coupling
Hui Hu, Xia-Ji Liu
We theoretically investigate the inhomogeneous Fulde-Ferrell (FF) superfluidity in a three dimensional atomic Fermi gas with Rashba spin-orbit coupling near a broad Feshbach resona…
Many-body \textit{T}-matrix theory of a strongly interacting spin-orbit coupled Fermi gas: Momentum-resolved radio-frequency spectroscopy and fermionic pairing
Hui Hu, Han Pu, Jing Zhang +1
Interacting Fermi gases with spin-orbit coupling are responsible for many intriguing phenomena such as topological superfluids and Majorana fermions. Here we characterize theoretic…
Radio-frequency spectroscopy of a strongly interacting spin-orbit coupled Fermi gas
Zhengkun Fu, Lianghui Huang, Zengming Meng +5
We investigate experimentally and theoretically radio-frequency spectroscopy and pairing of a spin-orbit-coupled Fermi gas of K atoms near a Feshbach resonance at $B_{0}=202…
