Homogeneous Floquet time crystal protected by gauge invariance

Abstract

The authors show that lattice gauge theories can accommodate nonequilibrium phases with long-range order. Specifically, the paper finds that they can feature Floquet time-crystal phases whose protection is not enforced by disorder but rather by gauge invariance.

Fractal nature of high-order time crystal phases

Guido Giachetti, Andrea Solfanelli, Lorenzo Correale +1 more

In Floquet time crystals, characterized by the spontaneous breaking of time-translational invariance, observables exhibit oscillations with a period multiple $p>2$ of the driving. Here, a new, experimentally accessible, order parameter is introduced, able to detect time-crystalline phases regardless of the value of $p$. This unveils a rich landscape with self-similar fractal boundaries in the phase diagram of the long-range kicked Ising model. These features are explained within the theoretical framework, along with the emergence of the ${Z}_{p}$ symmetry in Bloch eigenstates.

Floquet time crystals as quantum sensors of ac fields

Fernando Iemini, Rosario Fazio, Anna Sanpera

The authors investigate the use of time-crystal phases for metrology, providing a concrete proposal as quantum sensors of AC fields. Their performance shows several useful advantages due to their long-range spatiotemporal ordering, overcoming the shot noise limit along with long interrogation times and robustness.

Time Crystals Protected by Floquet Dynamical Symmetry in Hubbard Models

Koki Chinzei, Tatsuhiko N. Ikeda

We investigate an unconventional symmetry in time-periodically driven systems, the Floquet dynamical symmetry (FDS). Unlike the usual symmetries, the FDS gives symmetry sectors that are equidistant in the Floquet spectrum and protects quantum coherence between them from dissipation and dephasing, leading to two kinds of time crystals: the discrete time crystal and discrete time quasicrystal that have different periodicity in time. We show that these time crystals appear in the Bose- and Fermi-Hubbard models under ac fields and their periodicity can be tuned only by adjusting the strength of the field. These time crystals arise only from the FDS and thus appear in both dissipative and isolated systems and in the presence of disorder as long as the FDS is respected. We discuss their experimental realizations in cold atom experiments and generalization to the SU(N)-symmetric Hubbard models.

Clean Floquet Time Crystals: Models and Realizations in Cold Atoms

Biao Huang, Ying-Hai Wu, W. Vincent Liu

Time crystals, a phase showing spontaneous breaking of time-translation symmetry, has been an intriguing subject for systems far away from equilibrium. Recent experiments found such a phase in both the presence and the absence of localization, while in theories localization by disorder is usually assumed a priori. In this work, we point out that time crystals can generally exist in systems without disorder. A series of clean quasi-one-dimensional models under Floquet driving are proposed to demonstrate this unexpected result in principle. Robust time crystalline orders are found in the strongly interacting regime along with the emergent integrals of motion in the dynamical system, which can be characterized by level statistics and the out-of-time-ordered correlators. We propose two cold atom experimental schemes to realize the clean Floquet time crystals, one by making use of dipolar gases and another by synthetic dimensions.

Phase structure of one-dimensional interacting Floquet systems. I. Abelian symmetry-protected topological phases

Curt W. von Keyserlingk, Shivaji L. Sondhi

Phases of matter are traditionally seen as families of static systems exhibiting the same long-distance and low-energy correlations. In this work, the authors propose and classify a new family of phases of matter. They are novel insofar as they are intrinsically driven and out of equilibrium --- they can only be realized in systems with time-dependent Hamiltonians. The phases we consider arise in 1D periodically driven systems, in the presence of strong disorder and interactions, and are similar to but qualitatively distinct from the symmetry-protected topological phases now well known in the equilibrium setting. In a companion paper, the authors examine similar intrinsically driven families of states with long-range order, and an order parameter that oscillates at a frequency that is robustly an integer multiple of the underlying drive frequency.

Floquet time crystals in clock models

Federica Maria Surace, Angelo Russomanno, Marcello Dalmonte +3 more

We construct a class of period-$n$-tupling discrete time crystals based on ${\mathbb{Z}}_{n}$ clock variables, for all the integers $n$. We consider two classes of systems where this phenomenology occurs: disordered models with short-range interactions and fully connected models. In the case of short-range models, we provide a complete classification of time-crystal phases for generic $n$. For the specific cases of $n=3$ and $n=4$, we study in detail the dynamics by means of exact diagonalization. In both cases, through an extensive analysis of the Floquet spectrum, we are able to fully map the phase diagram. In the case of infinite-range models, the mapping onto an effective bosonic Hamiltonian allows us to investigate the scaling to the thermodynamic limit. After a general discussion of the problem, we focus on $n=3$ and $n=4$, representative examples of the generic behavior. Remarkably, for $n=4$ we find clear evidence of a crystal-to-crystal transition between period $n$-tupling and period $n/2$-tupling.
