Floquet-sideband-enhanced shortwave electrometry with Rydberg atoms
Jiaqi Yuan, Yunlong Xue, Yongjie Cheng +7
Rydberg atomic electric-field sensors, under the framework of optical excitation and readout, can overcome the size-to-wavelength constraint imposed by the Chu limit. However, thei…
Entanglement-enabled Criticality in One-dimensional Quantum Contact Process
Ya-Xin Xiang, Tianyi Yan, Weibin Li +1
The contact process is a paradigmatic example of nonequilibrium dynamics, with broad applications ranging from chemistry to sociology. Its quantum counterpart, the quantum contact…
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…
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…
