Quantum synchronization and entanglement generation
A Roulet, C Bruder - Physical review letters, 2018 - APS
We study synchronization in a two-node network built out of the smallest possible self-
sustained oscillator: a spin-1 oscillator. We first demonstrate that phase locking between the …

Quantum Origin of Limit Cycles, Fixed Points, and Critical Slowing Down
Among the most iconic features of classical dissipative dynamics are persistent limit-cycle
oscillations and critical slowing down at the onset of such oscillations, where the system …

Nonequilibrium criticality at the onset of time-crystalline order
We explore the phase transitions at the onset of time-crystalline order in O (N) models driven
out of equilibrium. The spontaneous breaking of time translation symmetry and its Goldstone …
