Collective quantum stochastic resonance in Rydberg atoms
Haowei Li, Konghao Sun, Wei Yi
We study the collective response of a group of dissipative Rydberg atoms to a periodic modulation of the Rydberg excitation laser. Focusing on the emergent collective-jump dynamics…
Higher-order Liouvillian exceptional points in the dissipative dynamics of quadratic fermions
Mingtao Xu, Wei Yi
We propose a general class of open fermionic models where quadratic Liouvillians governing the dissipative dynamics feature analytically characterized higher-order exceptional poin…
Symmetry-induced fragmentation and dissipative time crystal
Haowei Li, Wei Yi
Time crystals are a peculiar state of matter. Their emergence hinges on ergodicity breaking, which typically originates from many-body localization or Floquet prethermalization. He…
Bridging the classical and quantum regimes in a dissipative Ising chain
Zhenming Zhang, Haowei Li, Wei Yi
We study the long-time dynamics of a dissipative Ising chain with varying quantum correlation. Invoking an ensemble-average formalism, and assuming spatial translation symmetry, we…
Parametrically Driven Superradiance of an Interacting Tavis-Cummings Model
Wen-Jie Geng, Yiwen Han, Wei Yi
We consider the superradiant transition of a generalized Tavis-Cummings model, where a number of two-level qubits are coupled to a dissipative cavity. The cavity is coherently driv…
Cavity-Mediated Gas-Liquid Transition
Fan Zhang, Haowei Li, Wei Yi
We study the gas-liquid transition in a binary Bose-Einstein condensate, where the two Zeeman-shifted hyperfine spin components are coupled by cavity-assisted Raman processes. Belo…
