Spin evolution of cold atomic gases in SU(2)$\otimes $U(1) fields

I. V. Tokatly, E. Ya. Sherman

摘要:

本文研究了自旋-轨道耦合冷原子气体在只影响原子轨道运动的人工规范磁场中的响应函数和自旋演化。我们证明,各种制度的自旋轨道耦合强度,磁场,和无序可以在一个单一的方法的基础上表示的原子运动的辅助集体经典轨迹。我们的方法允许一个统一的描述费米子和玻色子气体。

英文摘要:

We consider response function and spin evolution in spin-orbit coupled cold atomic gases in a synthetic gauge magnetic field influencing solely the orbital motion of atoms. We demonstrate that various regimes of spin-orbit coupling strength, magnetic field, and disorder can be treated within a single approach based on the representation of atomic motion in terms of auxiliary collective classical trajectories. Our approach allows for a unified description of fermionic and bosonic gases.
