Quasi-adiabatic dynamics and state preparation in Floquet many-body systems

Understand

Periodic driving has emerged as a powerful experimental tool to engineer physical properties of isolated, synthetic quantum systems.

• However, due to the lack of energy conservation and heating effects, non-trivial (e.g., topological) many-body states in periodically driven (Floquet) systems are generally metastable.
• Therefore it is necessary to find strategies for preparing long-lived many-body states in Floquet systems.
• We develop a theoretical framework for describing the dynamical preparation of states in Floquet systems by a slow turn-on of the drive.
