摘要
自旋轨道耦合的超冷原子系统是模拟颤动的优秀平台。目前,实验对颤动的研究限制在两组分系统中,而已有的基于三组分理论的自旋轨道耦合均不利于实验实现。为此,基于实验已经实现的三组分自旋轨道耦合系统分析颤动,揭示了颤动具有多个振荡频率,当存在简谐束缚势时,颤动表现出丰富的物理内容。
Abstract
Spin-orbit-coupled ultracold atom system becomes an important platform to simulate Zitterbewegung. Current experimental study of Zitterbewegung is in a two-component atomic system, while the existed three-component theoretical study on spin-orbit coupling is difficult to realize in experiments. In this paper, based on the experimentally realizable three-component spin-orbit-coupled system, we analyze the Zitterbewegung and reveal that the Zitterbewegung has many oscillation frequencies. In the presence of harmonic trap potentials, Zitterbewegung oscillation possesses more rich physical characters.
