Strongly interacting Rydberg atoms in synthetic dimensions with a magnetic flux
Tao Chen, Chenxi Huang, Ivan Velkovsky +3
Synthetic dimensions, wherein dynamics occurs in a set of internal states, have found great success in recent years in exploring topological effects in cold atoms and photonics. Ho…
