Time-periodic driving: Floquet engineering beyond the high-frequency approximation (A05)

• Subject Area: Theoretical Condensed Matter Physics
• Term: since 2016
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 277625399

Using Floquet theory, time-periodic driving of quantum systems will be analyzed to uncover novel resonance effects and steady state correlations. Going beyond the usual high-frequency approximation, we will establish the full solution for selected many-body systems analytically and using our own newly developed numerical Floquet-DMRG in order to take many-body dynamics to the next level of quantum engineering. In the framework of OSCAR collaborations we will furthermore consider weakly-interacting driven systems in order to address issues of stability, heating, and accessibility of the steady states.
