Floquet engineering, i.e. driving the system with periodic Hamiltonians, not only provides great flexibility in analog quantum simulation, but also supports phase structures of great richness. It has been proposed that Floquet systems can support a discrete time-translation symmetry (TTS) broken phase, dubbed the discrete time crystal (DTC). This proposal, as well as the exotic phase, has attracted tremendous interest among the community of quantum simulation. Here we report the observation of… Expand

Realization of a discrete time crystal on 57 qubits of a quantum computer
Novel dynamical phases that violate ergodicity have been a subject of extensive research in recent years. A periodically driven system is naively expected to lose all memory of its initial state dueExpand
A comment on"Discrete time crystals: rigidity, criticality, and realizations"
The Letter by N. Y. Yao et. al. [1, 2] presents three models for realizing a many-body localized discrete time-crystal (MBL DTC): a short-ranged model [1], its revised version [2], as well as aExpand

Observation of Time-Crystalline Eigenstate Order on a Quantum Processor
Quantum many-body systems display rich phase structure in their low-temperature equilibrium states. However, much of nature is not in thermal equilibrium. Remarkably, it was recently predicted thatExpand
Simulating a discrete time crystal over 57 qubits on a quantum computer

Discrete Time Crystals: Rigidity, Criticality, and Realizations.
TLDR
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. Expand
Observation of discrete time-crystalline order in a disordered dipolar many-body system
TLDR
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. Expand
Observation of a discrete time crystal
TLDR
The experimental observation of a discrete time crystal, in an interacting spin chain of trapped atomic ions, is presented, which opens the door to the study of systems with long-range spatio-temporal correlations and novel phases of matter that emerge under intrinsically non-equilibrium conditions.

Many-body localization in periodically driven systems.
TLDR
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. Expand
Absolute stability and spatiotemporal long-range order in Floquet systems
Recent work has shown that a variety of novel phases of matter arise in periodically driven Floquet systems. Among these are many-body localized phases which spontaneously break global symmetries andExpand
Long-time behavior of periodically driven isolated interacting lattice systems
We study the dynamics of isolated interacting spin chains that are periodically driven by sudden quenches. Using full exact diagonalization of finite chains, we show that these systems exhibit threeExpand
Phase Structure of Driven Quantum Systems.
TLDR
It is shown that their disordered Floquet many-body localized counterparts can exhibit distinct ordered phases delineated by sharp transitions, and these are analogs of equilibrium states with broken symmetries and topological order. Expand
