• Abstract summary: We propose a model for quantum metamorphism between two DTCs of different periodicity, a 2T and 4T-DTC. Conditions for metamorphism come from the modulation of perturbative terms in the 4T-DTC Hamiltonian that gradually melt its structure and transform it into a 2T-DTC. We also propose a protocol to experimentally observe quantum metamorphism using current quantum technology.

• Abstract: Crystals form regular and robust structures that under extreme conditions can melt and recrystallize into different arrangements in a process that is called crystal metamorphism. While crystals exist due to the breaking of a continuous translation symmetry in space, it has recently been proposed that discrete crystalline order can also emerge in time and give raise to a novel phase of matter named discrete time crystal (DTC). In this paper, we join these two ideas and propose a model for quantum metamorphism between two DTCs of different periodicity, a 2T and 4T-DTC. In our model the conditions for metamorphism come from the modulation of perturbative terms in the 4T-DTC Hamiltonian that gradually melt its structure and transform it into a 2T-DTC. This process is studied in detail from the viewpoint of manybody physics of periodically driven systems. We also propose a protocol to experimentally observe quantum metamorphism using current quantum technology.

  Key step is to convert 3D crystal structures into 1D sequences to be processed by language models (LMs) Mat2Seq converts 3D crystal structures into 1D sequences and ensures that different mathematical descriptions of the same crystal are represented in a single unique sequence. Experimental results show that, with language models, Mat2Seq achieves promising performance in crystal structure generation as compared with prior methods.

  We study time-crystalline order in periodically driven quantum Ising models on disorder-free decorated lattices. We show through finite entanglement scaling that the system has an exponentially long-lived subharmonic response in the thermodynamic limit. Our results thus uncover a variety of time crystals which may be realized on current digital quantum processors and analog quantum simulators.

  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 show how photon-mediated interactions give rise to a plaquette-ordered bond pattern in the atomic ground state. The pattern opens a non-trivial topological gap in 2D, resulting in a higher-order topological phase hosting corner states. Our work shows how atomic quantum simulators can be harnessed to investigate novel strongly-correlated topological phenomena.

  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.
