Prethermal time crystal Characterizing and understanding different phases of matter in equilibrium is usually associated with the process of thermalization, where the system equilibrates. Recent efforts probing nonequilibrium systems have revealed that periodic driving of the system can suppress the natural tendency for equilibration yet still form new, nonequilibrium phases. Kyprianidis et al. used a quantum simulator composed of 25 trapped ion qubits and spins to observe such a nonequilibrium… 

Classical prethermal discrete time crystals

We demonstrate that the prethermal regime of periodically-driven, classical many-body systems can host non-equilibrium phases of matter. In particular, we show that there exists an effective

Route to Extend the Lifetime of a Discrete Time Crystal in a Finite Spin Chain without Disorder

Periodically driven (Floquet) systems are described by time-dependent Hamiltonians that possess discrete time translation symmetry. The spontaneous breaking of this symmetry leads to the emergence of

Suppression of heating by long-range interactions in periodically driven spin chains

We propose a mechanism to suppress heating in periodically driven many-body quantum systems by employing sufficiently long-range interactions and experimentally relevant initial conditions. The

Energy diffusion and absorption in chaotic systems with rapid periodic driving

The authors establish the diffusive evolution of energy in chaotic, ergodic Hamiltonian systems subject to rapid periodic driving, and connect this diffusion process to Floquet prethermalization,

Digital simulation of non-Abelian anyons with 68 programmable superconducting qubits

Non-Abelian anyons are exotic quasiparticle excitations hosted by certain topological phases of matter 2]. They break the fermion-boson dichotomy and obey non-Abelian braiding statistics [3–5]: their

Hilbert space fragmentation and interaction-induced localization in the extended Fermi-Hubbard model

We study Hilbert space fragmentation in the extended Fermi-Hubbard model with nearest and next-nearest neighbor interactions. Using a generalized spin/mover picture and saddle point meth-ods, we

Prethermalization and the local robustness of gapped systems

We prove that prethermalization is a generic property of gapped local many-body quantum systems, subjected to small perturbations, in any spatial dimension. More precisely, let H 0 be a Hamiltonian,

Engineering dynamically decoupled quantum simulations with trapped ions

An external drive can improve the coherence of a quantum many-body system by averaging out noise sources. It can also be used to realize models that are inaccessible in the static limit, through

Photonic Analogue of a Continuous Time Crystal

Time crystals are an eagerly sought phase of matter in which time-translation symmetry is broken. Quantum time crystals with discretely broken time-translation symmetry have been demonstrated in

'Prethermalization' in Conservative Nonsymplectic Periodically Driven Spin Systems

We analyze a new class of time-periodic dynamics in interacting chaotic classical spin systems, whose equations of motion are conservative (phase-space volume preserving) yet possess no symplectic

We propose and analyze a new method for quantum metrology based on stable non-equilibrium states of quantum matter. Our approach utilizes quantum correlations stabilized by strong interactions and
