Driven-Floquet and Quenched systems

Application of continuous or pulsed drive can dramatically change system properties.

For instance, continuous drive can convert topo-trivial band-structures into topo-non-trivial. Moreover, driving can be used to change the effective dimensionality of the systems, allowing to construct wide range of hamiltonians, even starting from 0D physical system, e.g. spin 1/2.

Quenching between topological and non-topological states can lead to lingering topological properties, e.g. persistent Hall current.
