Driven-Floquet and Quenched systems

Created about 10 years ago, updated about 10 years ago

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.
