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…
Quantum Zeno Effect in the Spatial Evolution of a Single Atom
Zheng-Yuan Zhang, Han-Chao Chen, Xin Liu +15
The quantum Zeno effect (QZE) reveals that frequent measurements can suppress quantum evolution, but the detailed dynamics of the system under finite-duration measurements in exper…
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…
