# Pre-thermal phases of matter protected by time-translation symmetry

@article{Else2016PrethermalPO, title={Pre-thermal phases of matter protected by time-translation symmetry}, author={Dominic Victor Else and Bela Bauer and C. Nayak}, journal={arXiv: Statistical Mechanics}, year={2016} }

In a periodically driven (Floquet) system, there is the possibility for new phases of matter, not present in stationary systems, protected by discrete time-translation symmetry. This includes topological phases protected in part by time-translation symmetry, as well as phases distinguished by the spontaneous breaking of this symmetry, dubbed "Floquet time crystals". We show that such phases of matter can exist in the pre-thermal regime of periodically-driven systems, which exists generically…
