Previous realizations of synthetic gauge fields for ultracold atoms do not allow the spatial
profile of the field to evolve freely. We propose a scheme which overcomes this restriction by …

Topological states of interacting many-body systems are at the focus of current research due
to the exotic properties of their elementary excitations. In this paper we suggest a realistic …

Periodically driven quantum systems can exhibit topologically nontrivial behavior, even
when their quasienergy bands have zero Chern numbers. Much work has been conducted …
