The periodic drive can be internal or external. An external drive might, for example, be an external laser field. An internal drive means the system itself is changing, such as the position or potential depth of lattice sites. Floquet systems can exhibit interesting effects, which would be impossible in static systems. This thesis investigates the influence of interaction on three Floquet systems.
