- Abstract: Floquet engineering is the concept of tailoring a system by a periodic drive.
It has been very successful in opening new classes of Hamiltonians to the study
with ultracold atoms in optical lattices, such as artificial gauge fields,
topological band structures and density-dependent tunneling. Furthermore,
driven systems provide new physics without static counterpart such as anomalous
Floquet topological insulators. In this review article, we provide an overview
of the exciting developments in the field and discuss the current challenges
and perspectives.

We propose a scheme to realize unconventional Floquet topological phases by engineering local band structures in particular momentum subspace called band surfaces (BISs)
This scheme is based on a new bulk-boundary correspondence that for a class of generic $d$-dimensional periodically driven systems, the local topological structure formed in each BIS uniquely determines the features of gapless boundary modes.
