Discrete time-crystals are periodically driven quantum many-body systems with broken discrete time translational symmetry, a non-equilibrium steady state representing self-organization of motion of quantum particles. Observations of discrete time-crystalline order are currently limited to magneto-optical experiments and it was never observed in a transport experiment performed on systems connected to external electrodes. Here we demonstrate that both discrete time-crystal and quasi-crystal…

Protecting coherence from the environment via Stark many-body localization in a Quantum-Dot Simulator

Semiconductor platforms are emerging as promising architecture for storing and processing quantum information, e.g., in quantum dot spin qubits. However, charge noise coming from interactions between

Non-Hermitian quantum gases: a platform for imaginary time crystals

One of the foremost objectives of statistical mechanics is the description of the thermodynamic properties of quantum gases. Despite the great importance of this topic, such achievement is still



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.

Time crystallinity in open quantum systems

A way to identify an open system time crystal based on a single object: the Floquet propagator is proposed and time-crystalline behavior in an explicitly short-range interacting open system is shown and the crucial role of the nature of the decay processes is demonstrated.

Observation of a discrete time crystal

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.

AC Josephson effect between two superfluid time crystals

Two adjacent quantum time crystals implemented by two magnon condensates in the superfluid B-phase of helium-3 are observed to coherently exchange magnons as a manifestation of the AC Josephson effect, offering insights on the dynamics and interactions between these phases of matter.

Time-crystalline eigenstate order on a quantum processor

Quantum many-body systems display rich phase structure in their low-temperature equilibrium states1. However, much of nature is not in thermal equilibrium. Remarkably, it was recently predicted that

Dicke time crystals in driven-dissipative quantum many-body systems

The Dicke model—a paradigmatic example of superradiance in quantum optics—describes an ensemble of atoms which are collectively coupled to a leaky cavity mode. As a result of the cooperative nature

Non-stationary coherent quantum many-body dynamics through dissipation

Conditions under which dissipation prevents quantum many-body systems from reaching a steady state are identified and they instead exhibit coherent oscillations, a dissipative version of a quantum time crystal.

Quantum simulation of a Fermi–Hubbard model using a semiconductor quantum dot array

It is shown that for gate-defined quantum dots this disorder can be suppressed in a controlled manner and a detailed characterization of the collective Coulomb blockade transition is realized, which is the finite-size analogue of the interaction-driven Mott metal-to-insulator transition.

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.

Conduction of Ultracold Fermions Through a Mesoscopic Channel

A cold-atom analog of a mesoscopic conductor is engineered and studied and induced a current through the channel and found ohmic conduction, even when the channel is ballistic, which opens the way toward quantum simulation of mesoscopic devices with quantum gases.
