This is a list of short pieces of code for the calculation of the Floquet spectrum of laser-illuminated graphene. The Floquet spectrum in such systems can be accessed experimentally with time-resolved ARPES techniques and has been the focus of great interest in the last years. Furthermore, this is the basis for the analysis of many transport experiments, which could be simulated with similar techniques. This code is meant for educational purposed only, use it at your risk.
