Floquet symmetry-protected topological phases in cold atomic systems
Ionut-Dragos Potirniche, Andrew C. Potter, Monika Schleier-Smith +2
We propose and analyze two distinct routes toward realizing interacting symmetry-protected topological (SPT) phases via periodic driving. First, we demonstrate that a driven transv…
Observation of a Discrete Time Crystal
J. Zhang, P. W. Hess, A. Kyprianidis +9
Spontaneous symmetry breaking is a fundamental concept in many areas of physics, ranging from cosmology and particle physics to condensed matter. A prime example is the breaking of…
Discrete time crystals: rigidity, criticality, and realizations
Norman Y. Yao, Andrew C. Potter, Ionut-Dragos Potirniche +1
Despite being forbidden in equilibrium, spontaneous breaking of time translation symmetry can occur in periodically driven, Floquet systems with discrete time-translation symmetry.…
