Random Multipolar Driving: Tunably Slow Heating through Spectral Engineering

Driven quantum systems may realize novel phenomena absent in static systems, but driving-induced heating can limit the time-scale on which these persist. We study heating in interacting quantum many-body systems driven by random sequences with n-ultipolar correlations, corresponding to a polynomially suppressed low frequency spectrum. For n\geq1 we find a prethermal regime, the lifetime of which grows algebraically with the driving rate,...
