We focus on the driven dynamics of a quantum system of noninteracting particles in a d-dimensional lattice, subjected to a periodically varying, time-dependent Hamil-tonian H!t", which satisﬁes H!t+T"=H!t". Here T is the pe-riod of the driving cycle. WebWe thus extend the notion of prethermal dynamics, observed in the high-frequency limit of periodically-driven systems, to a nonsymplectic setting. We analyze a new class of time-periodic dynamics in interacting chaotic classical spin systems, whose equations of motion are conservative (phase-space volume preserving) yet possess no symplectic ... ethical heels
