Reinforcement learning for autonomous preparation of floquet-engineered states: Inverting the quantum kapitza oscillator

M Bukov - Physical Review B, 2018 - APS
I demonstrate the potential of reinforcement learning (RL) to prepare quantum states of
strongly periodically driven nonlinear single-particle models. The ability of Q-learning to …

Asymptotic prethermalization in periodically driven classical spin chains

O Howell, P Weinberg, D Sels, A Polkovnikov… - Physical review letters, 2019 - APS
We reveal a continuous dynamical heating transition between a prethermal and an infinite-

Stability and pre-thermalization in chains of classical kicked rotors

A Rajak, R Citro, EG Dalla Torre - Journal of Physics A …, 2018 - iopscience.iop.org
Periodic drives are a common tool to control physical systems, but have a limited
applicability because time-dependent drives generically lead to heating. How to prevent the …

From prethermalization to chaos in periodically driven coupled rotors

Y Sadia, EG Dalla Torre, A Rajak - Physical Review B, 2022 - APS
Periodically driven (Floquet) systems are said to prethermalize when their energy absorption
is very slow for a long time. This effect was first discovered in quantum spin models, where …
