Thermalization and Prethermalization in Periodically Kicked Quantum Spin Chains
Christoph Fleckenstein, Marin Bukov
We study the dynamics of periodically-kicked many-body systems away from the high-frequency regime, and discuss a family of Floquet systems where the notion of prethermalization ca…
Prethermalization and Thermalization in Periodically-Driven Many-Body Systems away from the High-Frequency Limit
Christoph Fleckenstein, Marin Bukov
We investigate a class of periodically driven many-body systems that allows us to extend the phenomenon of prethermalization to the vicinity of isolated intermediate-to-low drive f…
Reinforcement learning for autonomous preparation of Floquet-engineered states: Inverting the quantum Kapitza oscillator
Marin Bukov
I demonstrate the potential of reinforcement learning (RL) to prepare quantum states of strongly periodically driven non-linear single-particle models. The ability of Q-Learning to…
Parametric instabilities in a 2D periodically-driven bosonic system: Beyond the weakly-interacting regime
T. Boulier, J. Maslek, M. Bukov +6
We experimentally investigate the effects of parametric instabilities on the short-time heating process of periodically-driven bosons in 2D optical lattices with a continuous trans…
Parametric instabilities of interacting bosons in periodically-driven 1D optical lattices
K. Wintersperger, M. Bukov, J. Näger +6
Periodically-driven quantum systems are currently explored in view of realizing novel many-body phases of matter. This approach is particularly promising in gases of ultracold atom…
QuSpin: a Python Package for Dynamics and Exact Diagonalisation of Quantum Many Body Systems. Part II: bosons, fermions and higher spins
Phillip Weinberg, Marin Bukov
We present a major update to QuSpin, SciPostPhys.2.1.003 -- an open-source Python package for exact diagonalization and quantum dynamics of arbitrary boson, fermion and spin many-b…
