Spin-orbital-angular-momentum-coupled quantum gases
Shi-Guo Peng, Kaijun Jiang, Xiao-Long Chen +3
We briefly review the recent progress of theories and experiments on spin-orbital-angular-momentum (SOAM)-coupled quantum gases. The coupling between the intrinsic degree of freedo…
Spin Josephson effects of spin-orbit-coupled Bose-Einstein condensates in a non-Hermitian double well
Jia Tang, Zhou Hu, Zhao-Yun Zeng +5
In this paper, we investigate the spin and tunneling dynamics of a spin-orbit-coupled noninteracting Bose-Einstein condensate in a periodically driven non-Hermitian double-well pot…
Molecular state in a spin-orbital-angular-momentum coupled Fermi gas
Yiwen Han, Shi-Guo Peng, Ke-Ji Chen +1
We study the two-body bound states in a spin-orbital-angular-momentum (SOAM) coupled quantum gas of fermions. Two different configurations are considered: an attractive -wave in…
Superfluidity of a Raman spin-orbit-coupled Bose gas at finite temperature
Xiao-Long Chen, Xia-Ji Liu, Hui Hu
We investigate the superfluidity of a three-dimensional weakly interacting Bose gas with a one-dimensional Raman-type spin-orbit coupling at both zero and finite temperatures. Usin…
Probing two Higgs oscillations in a one-dimensional Fermi superfluid with Raman-type spin-orbit coupling
Genwang Fan, Xiao-Long Chen, Peng Zou
We theoretically investigate the Higgs oscillation in a one-dimensional Raman-type spin-orbit-coupled Fermi superfluid with the time-dependent Bogoliubov-de Gennes equations. By li…
Angular topological superfluid and topological vortex in an ultracold Fermi gas
Ke-Ji Chen, Fan Wu, Lianyi He +1
We show that pairing in an ultracold Fermi gas under spin-orbital-angular-momentum coupling (SOAMC) can acquire topological characters encoded in the quantized angular degrees of f…
