• Abstract: The discrete time crystal (DTC) is a recently discovered phase of matter that spontaneously breaks time-translation symmetry. Disorder-induced many-body-localization is required to stabilize a DTC to arbitrary times, yet an experimental investigation of this localized regime has proven elusive. Here, we observe the hallmark signatures of a many-body-localized DTC using a novel quantum simulation platform based on individually controllable $^{13}$C nuclear spins in diamond. We demonstrate the characteristic long-lived spatiotemporal order and confirm that it is robust for generic initial states. Our results are consistent with the realization of an out-of-equilibrium Floquet phase of matter and establish a programmable quantum simulator based on solid-state spins for exploring many-body physics.

  Discrete time crystals (DTCs) are novel out-of-equilibrium quantum states of matter which break time translational symmetry. We develop an intuitive interacting spin-$1/2$ system that supports the more non-trivial period-quadrupling DTCs. We find a strong signature of the predicted $4T$-DTC that is robust against and, in some cases, amplified by different types of disorders.

  We consider the two-dimensional quantum Ising model, in absence of disorder, subject to periodic imperfect global spin flips. We show by a combination of exact diagonalization and tensor-network methods that the system can sustain a spontaneously broken discrete time-translation symmetry. We observe a non-perturbative change in the decay rate of the order parameter, which is related to the long-lived stability of the magnetic domains in 2D.

The dependence of the spectral function on the time after the pump pulse reveals collective interactions among spinons.
