Asymptotic Prethermalization in Periodically Driven Classical Spin Chains
Asymptotic Prethermalization in Periodically Driven Classical Spin Chains
We reveal a continuous dynamical heating transition between a prethermal and an infinite-temperature stage in a clean, chaotic periodically driven classical spin chain. The transition time is a steep exponential function of the drive frequency, showing that the exponentially long-lived prethermal plateau, originally observed in quantum Floquet systems, survives the …
