Abstract
The development of future quantum devices requires understanding the dynamics of driven many-body systems, in which the Floquet-induced interactions play a central role. This understanding is crucial for coherently controlling quantum states, minimising errors, and benchmarking the performance of these devices. In this thesis, we analyse the enhancement on the Floquet-induced interactions by many-body correlations, and develop an advanced Floquet method to understand the Floquet-induced interactions relevant for future quantum devices.
