倾斜光晶格中的拓扑相变

Topological phase transitions in tilted optical lattices

Andrey R. Kolovsky

摘要:

本文分析了倾斜砖墙光晶格中冷原子的能谱和本征态。当施加倾斜时,系统表现出一系列拓扑相变,反映在本征态的突变中。结果表明,这些拓扑相变可以很容易地检测在实验室实验中通过观察冷原子的布洛赫振荡。

英文摘要:

We analyze the energy spectrum and eigenstates of cold atoms in a tilted brick-wall optical lattice. When the tilt is applied, the system exhibits a sequence of topological phase transitions reflected in an abrupt change of the eigenstates. It is demonstrated that these topological phase transitions can be easily detected in a laboratory experiment by observing Bloch oscillations of cold atoms.
