Colloquium: Quantum and classical discrete time crystals
The spontaneous breaking of time-translation symmetry has led to the discovery of a new
phase of matter: the discrete time crystal. Discrete time crystals exhibit rigid subharmonic …

Time crystals: a review
Time crystals are time-periodic self-organized structures postulated by Frank Wilczek in
2012. While the original concept was strongly criticized, it stimulated at the same time an …

[BOOK][B] The Jaynes–Cummings model and its descendants: modern research directions
J Larson, T Mavrogordatos - 2021 - iopscience.iop.org
The Jaynes–Cummings Model (JCM) has recently been receiving increased attention as
one of the simplest, yet intricately nonlinear, models of quantum physics. Emphasising the …

Observation of discrete-time-crystal signatures in an ordered dipolar many-body system
J Rovny, RL Blum, SE Barrett - Physical review letters, 2018 - APS
A discrete time crystal (DTC) is a robust phase of driven systems that breaks the discrete
time translation symmetry of the driving Hamiltonian. Recent experiments have observed …

Boundary time crystals
In this work we introduce boundary time crystals. Here continuous time-translation symmetry
breaking occurs only in a macroscopic fraction of a many-body quantum system. After …
