Encircling the Liouvillian exceptional points: a brief review
Konghao Sun, Wei Yi
Exceptional points are the branch-point singularities of non-Hermitian Hamiltonians, and have rich consequences in open-system dynamics. While the exceptional points and their crit…
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…
Chiral switching of many-body steady states in a dissipative Rydberg gas
Chongwu Xie, Konghao Sun, Kang-Da Wu +4
Dissipative Rydberg gases are an outstanding platform for the investigation of many-body quantum open systems. Despite the wealth of existing studies, the non-equilibrium dynamics…
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…
