基于光晶格原子钟实现人造自旋轨道耦合的相关研究进展,简要说明利用光晶格原子钟实现自旋轨道耦合的基本原理。通过与传统实现自旋轨道耦合的拉曼耦合方案相比较,指出利用光晶格原子钟实现自旋轨道耦合方案的优越性。讨论了自旋轨道耦合光晶格原子钟在量子简并区域可能实现的奇异物态和新奇量子现象。强调了光钟平台在超冷原子新物态的制备、操控和测量等方面扮演的重要角色。

Based on the recent experimental realization of spin-orbit coupling in optical lattice clocks,we briefly introduce the experimental scheme for the generation of spin-orbit coupling.By comparing the optical-clock scheme and the traditional Raman scheme,we indicate the advantage of the former.We also discuss possible novel states of matter and quantum phenomena in the quantum degenerate regions,with emphasis on the important role played by the optical lattice clock in preparing,controlling and measuring new states of matter in ultra-cold atomic gases.
