We consider a dissipative quantum Ising model periodically driven by a train of π-pulses and investigate dissipative discrete time crystals (DTCs) in solids. In this model, the interaction between the spins spontaneously breaks the discrete time translation symmetry, giving rise to a dissipative DTC, where two ferromagnetic states are switched alternately by each pulse. We microscopically describe the generic dissipation due to thermal contact to an equilibrium heat bath using the BlochRedfield…

Exact bistability and time pseudo-crystallization of driven-dissipative fermionic lattices
The existence of bistability in quantum optical systems remains a intensely debated open question beyond the mean-field approximation. Quantum fluctuations are finite-size corrections to the
Out-of-Time-Ordered Crystals and Fragmentation
Is a spontaneous perpetual reversal of the arrow of time possible? The out-of-time-ordered correlator (OTOC) is a standard measure of irreversibility, quantum scrambling, and the arrow of time. The
Emergence and Dynamical Stability of a Charge Time-Crystal in a Current-Carrying Quantum Dot Simulator.
Periodically driven open quantum systems that never thermalize exhibit a discrete time-crystal behavior, a nonequilibrium quantum phenomenon that has shown promise in quantum information processing
Dynamical l-bits in Stark many-body localization
Stark many-body localized (SMBL) systems have been shown both numerically and experimentally to have Bloch many-body oscillations, quantum many-body scars, and fragmentation in the large field tilt


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.
Signatures of discrete time crystalline order in dissipative spin ensembles
Discrete time-translational symmetry in a periodically driven many-body system can be spontaneously broken to form a discrete time crystal, an exotic new phase of matter. We present observations
Classical stochastic discrete time crystals.
It is speculated that systems with thermal phase transitions to multiple competing phases can give rise to DTCs when appropriately driven, and it is explicitly shown that the DTC is a genuine nonequilibrium state.
Thermal melting of discrete time crystals: A dynamical phase transition induced by thermal fluctuations
The stability of a discrete time crystal against thermal fluctuations has been studied numerically by solving a stochastic Landau-Lifshitz-Gilbert equation of a periodically-driven classical system
Discrete Time Crystals in the Absence of Manifest Symmetries or Disorder in Open Quantum Systems.
A semiclassical approach reveals the emergence of a robust discrete time-crystalline phase in the thermodynamic limit in which metastability, dissipation, and interparticle interactions play a crucial role.
Time crystallinity in dissipative Floquet systems
We investigate the conditions under which periodically driven quantum systems subject to dissipation exhibit a stable subharmonic response. Noting that coupling to a bath introduces not only cooling
Critical Time Crystals in Dipolar Systems.
The authors demonstrate the existence of a novel, critical DTC regime that is stabilized not by many-body localization but rather by slow, critical dynamics, and shows that the DTC response can be used as a sensitive probe of nonequilibrium quantum 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.
Electronic Floquet gyro-liquid crystal
It is demonstrated that coherent driving can be used to induce non-equilibrium quantum phases of matter with dynamical broken symmetry in lightly doped semiconductors.
