We explore the response of many-body localized (MBL) systems to periodic driving of arbitrary amplitude, focusing on the rate at which they exchange energy with the drive. To this end, we introduce an infinite-temperature generalization of the effective “heating rate” in terms of the spread of a random walk in energy space. We compute this heating rate numerically and estimate it analytically in various regimes. When the drive amplitude is much smaller than the frequency, this effective heating… Expand

Floquet prethermalization and regimes of heating in a periodically driven, interacting quantum system
The results demonstrate the parametric stability of prethermal states in a many-body system driven at frequencies that are comparable to its microscopic scales, which paves the way for realizing exotic quantum phases, such as time crystals or interacting topological phases, in the preThermal regime of interacting Floquet systems.

Dynamics and transport at the threshold of many-body localization
Many-body localized (MBL) systems do not approach thermal equilibrium under their intrinsic dynamics; MBL and conventional thermalizing systems form distinct dynamical phases of matter, separated byExpand
Stability of electric field driven many-body localization in an interacting long-range hopping model
We study the fate of many-body localization (MBL) in the presence of long-range hopping ($\sim 1/r^{\sigma}$) in a system subjected to an electric field (static and time-periodic) along with aExpand
Mott, Floquet, and the response of periodically driven Anderson insulators
We consider periodically driven Anderson insulators. The short-time behavior for weak, monochromatic, uniform electric fields is given by linear response theory and was famously derived by Mott. WeExpand
Anomalous thermalization and transport in disordered interacting Floquet systems
Local observables in generic periodically driven closed quantum systems are known to relax to values described by periodic infinite temperature ensembles. At the same time, ergodic static systemsExpand
Rare‐region effects and dynamics near the many‐body localization transition
The low-frequency response of systems near the many-body localization phase transition, on either side of the transition, is dominated by contributions from rare regions that are locally “in theExpand
Numerical Methods for Many-Body Quantum Dynamics
A new truncation for matrix product operators is given, which reproduces local properties faithfully without reproducing non-local properties, and the utility of many-body localization as a medium for a thermodynamic engine is studied. Expand
Periodically Driven Sachdev-Ye-Kitaev Models.
While the NFL heats exponentially and thermalizes rapidly, it is reported that the presence of quasiparticles in the heavy FL obstructs heating and thermalization over comparatively long timescales. Expand
Two- and three-body problem with Floquet-driven zero-range interactions

Distinctive response of many-body localized systems to a strong electric field
We study systems that are close to or within the many-body localized (MBL) regime and are driven by a strong electric field. In the ergodic regime, the disorder extends the applicability of theExpand
Griffiths effects and slow dynamics in nearly many-body localized systems
The low-frequency response of systems near a many-body localization transition can be dominated by rare regions that are locally critical or “in the other phase.” It is known that in one dimension,Expand
Mean-field theory of nearly many-body localized metals
We develop a mean-field theory of the metallic phase near the many-body localization (MBL) transition, using the observation that a system near the MBL transition should become an increasingly slowExpand
A theory of many-body localization in periodically driven systems
We present a theory of periodically driven, many-body localized (MBL) systems. We argue that MBL persists under periodic driving at high enough driving frequency: The Floquet operator (evolutionExpand
Robustness of Many-Body Localization in the Presence of Dissipation.
It is found that, even though the system is eventually driven into an infinite-temperature state, heating as monitored by the von Neumann entropy can progress logarithmically slowly, implying exponentially large time scales for relaxation. Expand
Dynamics of a Many-Body-Localized System Coupled to a Bath.
This work considers two different types of dissipation relevant to systems of ultracold atoms: dephasing due to inelastic scattering on the lattice lasers and particle loss, and their different effects in the limiting cases of weak and strong interactions. Expand
Anomalous diffusion and griffiths effects near the many-body localization transition.
This work explores the high-temperature dynamics of the disordered, one-dimensional XXZ model near the many-body localization (MBL) transition, focusing on the delocalized (i.e., "metallic") phase, and establishes scaling relations between the associated exponents, assuming a scaling form of the spin-diffusion propagator.

Universal properties of many-body delocalization transitions
We study the dynamical melting of "hot" one-dimensional many-body localized systems. As disorder is weakened below a critical value these non-thermal quantum glasses melt via a continuous dynamicalExpand
Spectral features of a many-body-localized system weakly coupled to a bath

Quantum quenches in the many-body localized phase
Many-body localized (MBL) systems are characterized by the absence of transport and thermalization, and therefore cannot be described by conventional statistical mechanics. In this paper, usingExpand
