Observation of a Rydberg-atom time crystal with an ultralong lifetime
Qi-Feng Wang, Tian-Yu Han, Ya-Jun Wang +9
Continuous time crystals (CTCs) represent a nonequilibrium quantum phase that spontaneously breaks time-translation symmetry without periodic external driving, manifesting as persi…
Fingerprint Recognition of Partial Discharge Signals in Deep Learning Enhanced Rydberg Atomic Sensors
Yi-Ming Yin, Qi-Feng Wang, Yu Ma +16
Partial discharge originates from microscopic insulation imperfections in high-voltage apparatus and is widely considered a critical marker of incipient deterioration. Conventional…
Observation of non-Hermitian topology in cold Rydberg quantum gases
Jun Zhang, Ya-Jun Wang, Shi-Yao Shao +16
The pursuit of topological phenomena in non-Hermitian systems has unveiled new physics beyond the conventional Hermitian paradigm, yet their realization in interacting many-body pl…
Observation of Discrete Time Quasicrystal in Rydberg Atomic Gases
Dong-Yang Zhu, Zheng-Yuan Zhang, Qi-Feng Wang +17
Discrete time quasicrystals (DTQC) constitute a class of non-equilibrium matter characterized by temporal order without strict periodicity, in contrast to conventional time crystal…
Quantum enhanced metrology based on flipping trajectory of cold Rydberg gases
Ya-Jun Wang, Jun Zhang, Zheng-Yuan Zhang +17
The dynamical trajectory of a dissipative Rydberg many-body system could be flipped under a microwave field driving, displaying an enhanced sensitivity. This is because the interse…
