Floquet theory and topological classification of periodically driven systems

Álvaro Gómez León, Instituto de Ciencias de Materiales de Madrid, Spain

As an introduction, I will explain how to treat periodically driven systems by means of Floquet formalism, and the AZ topological classification of time independent system (gapped phases). Then, I will explain how the latter classfication can also be used for time dependent systems, and the differences with its static counter part.
