Quantum synchronization at the critical point of Floquet driven Rydberg atoms
Bang Liu, Li-Hua Zhang, Yu Ma +13
The criticality enhanced correlations and susceptibility allow weak periodic driving to induce collective synchronization due to critical slowing down, providing a unique platform…
Folded multistability and hidden critical point in microwave-driven Rydberg atoms
Yu Ma, Bang Liu, Li-Hua Zhang +13
The interactions between Rydberg atoms and microwave fields provide a valuable framework for studying the complex dynamics out of equilibrium, exotic phases, and critical phenomena…
Higher-order and fractional discrete time crystals in Floquet-driven Rydberg atoms
Bang Liu, Li-Hua Zhang, Qi-Feng Wang +9
Higher-order and fractional discrete time crystals (DTCs) are exotic phases of matter where the discrete time translation symmetry is broken into higher-order and non-integer categ…
Observation of Higgs and Goldstone modes in U(1) symmetry-broken Rydberg atomic systems
Bang Liu, Li-Hua Zhang, Ya-Jun Wang +13
Higgs and Goldstone modes manifest as fluctuations in the order parameter of system, offering insights into its phase transitions and symmetry properties. Exploring the dynamics of…
Early warning signals of the tipping point in strongly interacting Rydberg atoms
Jun Zhang, Li-Hua Zhang, Bang Liu +11
The identification of tipping points is essential for prediction of collapses or other sudden changes in complex systems. Applications include studies of ecology, thermodynamics, c…
Exceptional point and hysteresis trajectories in cold Rydberg atomic gases
Jun Zhang, En-Ze Li, Ya-Jun Wang +14
The interplay between strong long-range interactions and the coherent driving contribute to the formation of complex patterns, symmetry, and novel phases of matter in many-body sys…
