Dynamical Tipping in a Quantum Limit Cycle
Ya-Xin Xiang, Zhengyang Bai, Yu-Qiang Ma
Nonequilibrium systems maintain spatiotemporal order through energy dissipation and entropy production. Here, we demonstrate this principle by engineering a quantum limit cycle tha…
Quantum predator-prey cycles in dissipative Rydberg array
Ya-Xin Xiang, Weibin Li, Zhengyang Bai +1
The predator-prey cycle is a paradigmatic example of self-organized population oscillations in far-from-equilibrium systems, yet testing its underlying mechanism in natural ecosyst…
Switching Dynamics of Metastable Open Quantum Systems
Ya-Xin Xiang, Weibin Li, Zhengyang Bai +1
Classical metastability manifests as noise-driven switching between disjoint basins of attraction and slowing down of relaxation, quantum systems like qubits and Rydberg atoms exhi…
Self-Organized Time Crystal in Driven-Dissipative Quantum System
Ya-Xin Xiang, Qun-Li Lei, Zhengyang Bai +1
Continuous time crystals (CTCs) are characterized by sustained oscillations that break the time translation symmetry. Since the ruling out of equilibrium CTCs by no-go theorems, th…
