Cavity-induced generation of nontrivial topological states in a two-dimensional Fermi gas
Cavity-induced generation of nontrivial topological states in a two-dimensional Fermi gas
We propose how topologically nontrivial states can dynamically organize in a fermionic quantum gas that is confined to a two-dimensional optical lattice potential and coupled to the field of an optical cavity. The spontaneously emerging cavity field induces, together with coherent pump laser fields, a dynamical gauge field for the …
