Suppression of inter-band heating for random driving — •Hongzheng Zhao^1,2, Johannes Knolle^2,3,4, Roderich Moessner¹, and Florian Mintert² — ¹Max Planck Institute for the Physics of Complex Systems, Dresden, Germany — ²Imperial College London, London, United Kingdom — ³Technical University of Munich, Munich, Germany — ⁴Munich Center for Quantum Science and Technology, Munich, Germany

Heating to high-lying states strongly limits the experimental observation of driving induced non-equilibrium phenomena, particularly when the drive has a broad spectrum. Here we show that, for entire families of structured random drives known as random multipolar drives, particle excitation to higher bands can be well controlled even away from a high-frequency driving regime. This opens a window for observing drive-induced phenomena in a long-lived prethermal regime in the lowest band. Reference: arXiv:2201.08130
