Many-Body Physics with Rydberg Atoms: Quantum Simulation and Non-equilibrium Dynamics
Zhengyang Bai, Cheng Chen, Fan Yang +1
This review surveys recent theoretical and experimental progress in using strongly interacting Rydberg atoms to study many‑body physics, quantum simulation, and non‑equilibrium dyn…
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…
Enhanced Microwave Sensing with Dissipative Continuous Time Crystals
Yunlong Xue, Zhengyang Bai, Yu-Qiang Ma
A dissipative time crystal is an emergent phase in driven-dissipative quantum many-body systems, characterized by sustained oscillations that break time-translation symmetry sponta…
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…
Arbitrary Instantaneous Bandwidth Microwave Receiver via Scalable Rydberg Vapor Cell Array with Stark Comb
Yuechun Jiao, Yuwen Yin, Yunhui He +7
Rydberg atoms have great potential for microwave (MW) measurements due to their high sensitivity, broad carrier bandwidth, and traceability. However, the narrow instantaneous bandw…
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…
