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…

Interaction-Enhanced Superradiance of a Ryderg-Atom Array
Yiwen Han, Haowei Li, Wei Yi
We study the superradiant phase transition of an array of Rydberg atoms in a dissipative microwave cavity. Under the interplay of the cavity field and the long-range Rydberg intera…
