Aharonov-Casher Chern bands for ultracold dark state atoms

Domantas Burba, Dominykas Borodinas, Gediminas Juzeliūnas

We consider the Aharonov-Casher (AC) condition for ultracold atoms adiabatically following the dark-state in a $\Lambda$-type atom-light coupling scheme. The AC condition establishes a r…
