Figure 3: Powerlaw exponent α of the absorbed energy in the thermalizing regime.

From: Floquet prethermalization and regimes of heating in a periodically driven, interacting quantum system

The exponent α is extracted from the algebraic growth of the energy density at late times . With increasing interaction strength u and driving frequency Ω (but still within the single-particle band), the exponent α quickly approaches 1/2, suggesting that in the asymptotic long-time limit, t → ∞, the heating rate universally scales as .
