考虑自旋轨道耦合的正常原子气体的流体力学

Hydrodynamics of Normal Atomic Gases with Spin-orbit Coupling

Yan-Hua Hou, Zhenhua Yu

摘要:

NIST方案成功实现了原子气体中的自旋-轨道耦合,为以前所未有的可控方式研究自旋-轨道耦合对多体物理的影响开辟了前景。本文采用NIST方法,在零失谐条件下,导出了自旋-轨道耦合下正常原子气体的线性化流体动力学方程。我们表明,系统的流体动力学的关键取决于可以修改的自旋轨道耦合的动量磁化率。通过对理想费米气体的计算,揭示了自旋轨道耦合对气体的声速和偶极模频率的影响。我们还讨论了我们的结果推广到其他情况。

英文摘要:

Successful realization of spin-orbit coupling in atomic gases by the NIST scheme opens the prospect of studying the effects of spin-orbit coupling on many-body physics in an unprecedentedly controllable way. Here we derive the linearized hydrodynamic equations for the normal atomic gases of the spin-orbit coupling by the NIST scheme with zero detuning. We show that the hydrodynamics of the system crucially depends on the momentum susceptibilities which can be modified by the spin-orbit coupling. We reveal the effects of the spin-orbit coupling on the sound velocities and the dipole mode frequency of the gases by applying our formalism to the ideal Fermi gas. We also discuss the generalization of our results to other situations.
