Modified interactions in a Floquet topological system on a square lattice and their impact on a bosonic fractional Chern insulator state

Mantas Račiūnas, Giedrius Žlabys, André Eckardt +1

We propose a simple scheme for the realization of a topological quasienergy band structure with ultracold atoms in a periodically driven optical square lattice. It is based on a ci…
