We study the heating time in periodically driven D-dimensional systems with interactions that decay with the distance r as a power law 1 / r α . Using linear-response theory, we show that the heating time is exponentially long as a function of the drive frequency for α > D . For systems that may not obey linear-response theory, we use a more general Magnus-like expansion to show the existence of quasiconserved observables, which imply exponentially long heating time, for α > 2 D . We also…

Random Multipolar Driving: Tunably Slow Heating through Spectral Engineering.

Despite the absence of periodicity in the drive, and in spite of its eventual heat death, the prethermal regime can host versatile nonequilibrium phases, which is illustrated with a random multipolar discrete time crystal.

Prethermalization without Temperature

While a clean driven system generically absorbs energy until it reaches `infinite temperature', it may do so very slowly exhibiting what is known as a prethermal regime. Here, we show that the

Long-Lived Interacting Phases of Matter Protected by Multiple Time-Translation Symmetries in Quasiperiodically Driven Systems

We show how a large family of interacting nonequilibrium phases of matter can arise from the presence of multiple time-translation symmetries, which occur by quasiperiodically driving an isolated

Absence of Fast Scrambling in Thermodynamically Stable Long-Range Interacting Systems.

This study rigorously demonstrate that the OTOC shows a polynomial growth over time as long as α>D and the necessary scrambling time over a distance R is larger than t≳R^{[(2 α-2D)/(2α-D+1)]}.

A Brief History of Time Crystals.

The idea of breaking time-translation symmetry has fascinated humanity at least since ancient proposals of the perpetuum mobile. Unlike the breaking of other symmetries, such as spatial translation

Polynomial growth of out-of-time-order correlator in arbitrary realistic long-range interacting systems

This study rigorously demonstrate that the OTOC shows a polynomial growth over time as long as $\alpha>D$ and the necessary scrambling time over a distance $R$ is larger than $t\gtrsim R^{\frac{2 \alpha-2D}{2\alpha-D+1}}$.

Energy diffusion and prethermalization in chaotic billiards under rapid periodic driving.

The analysis suggests three phases of energy evolution: Prethermalization on short timescales, then slow energy absorption in accordance with the Fokker-Planck equation, and finally a breakdown of the rapid driving assumption for large energies and high particle speeds.

Lieb-Robinson bounds and out-of-time order correlators in a long-range spin chain

Lieb Robinson bounds quantify the maximal speed of information spreading in nonrelativistic quantum systems. We discuss the relation of Lieb Robinson bounds to out of time order correlators, which

Long-Range Prethermal Phases of Nonequilibrium Matter

We prove the existence of non-equilibrium phases of matter in the prethermal regime of periodically-driven, long-range interacting systems, with power-law exponent $\alpha > d$, where $d$ is the



Persistence of locality in systems with power-law interactions.

A new bound on the propagation of information in D-dimensional lattice models exhibiting 1/r^{α} interactions with α>D is derived, which qualitatively reproduce the short- and long-distance dynamical behavior following a local quench in an XY chain and a transverse-field Ising chain.

Bounds on Energy Absorption and Prethermalization in Quantum Systems with Long-Range Interactions.

It is shown that the disorder averaged energy absorption rate at high temperatures decays exponentially with the driving frequency, which strongly suggests the presence of a prethermal plateau in which dynamics is governed by an effective, static Hamiltonian for long times.

Nearly linear light cones in long-range interacting quantum systems.

This work rules out the possibility that light cones of power-law interacting systems are bounded by a polynomial for α>2D and become linear as α→∞, suggesting that the velocity, as calculated from the slope of the light cone, may grow exponentially in time.

Universal high-frequency behavior of periodically driven systems: from dynamical stabilization to Floquet engineering

We give a general overview of the high-frequency regime in periodically driven systems and identify three distinct classes of driving protocols in which the infinite-frequency Floquet Hamiltonian is

Exponentially Slow Heating in Periodically Driven Many-Body Systems.

It is shown that, for systems with local interactions, the energy absorption rate decays exponentially as a function of driving frequency in any number of spatial dimensions, implying that topological many-body states in periodically driven systems, although generally metastable, can have very long lifetimes.

Effective Hamiltonians, prethermalization, and slow energy absorption in periodically driven many-body systems

We establish some general dynamical properties of quantum many-body systems that are subject to a high-frequency periodic driving. We prove that such systems have a quasiconserved extensive quantity

Fast Quantum State Transfer and Entanglement Renormalization Using Long-Range Interactions.

This protocol realizes an exponential speedup in cases of α=d, which could be useful in creating large entangled states for dipole-dipole (1/r^{3}) interactions in three dimensions.

Spectral Gap and Exponential Decay of Correlations

We study the relation between the spectral gap above the ground state and the decay of the correlations in the ground state in quantum spin and fermion systems with short-range interactions on a wide
