Discrete time crystal (DTC) has recently attracted increasing attention, but most DTC models and their properties are only revealed after disorder average. In this Letter, we propose a simple disorder-free periodically driven model that exhibits nontrivial DTC order stabilized by Stark many-body localization (MBL). We demonstrate the existence of DTC phase by analytical analysis from perturbation theory and convincing numerical evidence from observable dynamics. The new DTC model paves a new…

Observation of discrete time-crystalline order in a disordered dipolar many-body system

This work observes long-lived temporal correlations, experimentally identifies the phase boundary and finds that the temporal order is protected by strong interactions, which opens the door to exploring dynamical phases of matter and controlling interacting, disordered many-body systems.

Discrete Time-Crystalline Order Enabled by Quantum Many-Body Scars: Entanglement Steering via Periodic Driving.

The results suggest a route to controlling entanglement in interacting quantum systems by combining periodic driving with many-body scars, and predict robustness to perturbations and identify emergent timescales that could be observed in future experiments.

Prethermal time crystals in a one-dimensional periodically driven Floquet system

Motivated by experimental observations of time-symmetry breaking behavior in a periodically driven (Floquet) system, we study a one-dimensional spin model to explore the stability of such Floquet

Many-body localization in periodically driven systems.

An effective model of the MBL phase is proposed in terms of an extensive number of emergent local integrals of motion, which naturally explains the spectral and dynamical properties of this phase.

Clean Floquet Time Crystals: Models and Realizations in Cold Atoms.

It is pointed out that time crystals can generally exist in systems without disorder, and a series of clean quasi-one-dimensional models under Floquet driving are proposed to demonstrate this unexpected result in principle.

Many-body–localized discrete time crystal with a programmable spin-based quantum simulator

The results are consistent with the realization of an out-of-equilibrium Floquet phase of matter and introduce a programmable quantum simulator based on solid-state spins for exploring many-body physics.

Discrete Time Crystals: Rigidity, Criticality, and Realizations.

A simple model for a one-dimensional discrete time crystal which explicitly reveals the rigidity of the emergent oscillations as the drive is varied is considered and a blueprint based upon a one dimensional chain of trapped ions is proposed.

Classical discrete time crystals

The spontaneous breaking of time-translation symmetry in periodically driven quantum systems leads to a new phase of matter: the discrete time crystal (DTC). This phase exhibits collective

Observation of a prethermal discrete time crystal

Floquet prethermalization is presented as a general strategy for creating, stabilizing, and studying intrinsically out-of-equilibrium phases of matter.

Discrete Time-Crystalline Order in Cavity and Circuit QED Systems.

A phenomenology of dissipative discrete time crystals is established by generalizing the Landau theory of phase transitions to Floquet open systems and finding clear signatures of a transient discrete time-crystalline behavior, which is absent in the isolated counterpart.
