Universal scattering phase shift in the presence of spin-orbit coupling
Cai-Xia Zhang, Shi-Guo Peng
Scattering phase shift, as a key parameter in scattering theory, plays an important role in characterizing low-energy collisions between ultracold atoms. In this work, we theoretic…
Interplay of nonreciprocity and nonlinearity on mean-field energy and dynamics of a Bose-Einstein condensate in a double-well potential
Yi-Piao Wu, Guo-Qing Zhang, Cai-Xia Zhang +2
We investigate the mean-field energy spectrum and dynamics in a Bose-Einstein condensate in a double-well potential with non-Hermiticity from the nonreciprocal hopping, and show th…
Universal relations for spin-orbit-coupled Fermi gases in two and three dimensions
Cai-Xia Zhang, Shi-Guo Peng, Kaijun Jiang
We present a comprehensive derivation of a set of universal relations for spin-orbit-coupled Fermi gases in three or two dimension, which follow from the short-range behavior of th…
Contact theory for spin-orbit-coupled Fermi gases
Shi-Guo Peng, Cai-Xia Zhang, Shina Tan +1
We develop the contact theory for spin-orbit-coupled Fermi gases. By using a perturbation method, we derive analytically the universal two-body behavior at short distance, which do…
