Pre-thermal phases of matter protected by time-translation symmetry
Dominic V. Else, Bela Bauer, Chetan Nayak
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. Th…
Ising Anyons in Frustration-Free Majorana-Dimer Models
Brayden Ware, Jun Ho Son, Meng Cheng +3
Dimer models have long been a fruitful playground for understanding topological physics. Here we introduce a new class - termed Majorana-dimer models - wherein bosonic dimers are d…
Floquet Time Crystals
Dominic V. Else, Bela Bauer, Chetan Nayak
We define what it means for time translation symmetry to be spontaneously broken in a quantum system, and show with analytical arguments and numerical simulations that this occurs…
Many-body localization in the presence of a small bath
Katharine Hyatt, James R. Garrison, Andrew C. Potter +1
In the presence of strong disorder and weak interactions, closed quantum systems can enter a many-body localized phase where the system does not conduct, does not equilibrate even…
