Chiral Entangled-State Generation through Dissipative Quantum Dynamics
Huixia Gao, Konghao Sun, Yiwen Han +6
Dissipation, though often detrimental to quantum entanglement, can be manipulated for the preparation of entangled states, wherein ingeniously designed quantum jump processes drive…
Photonic chiral state transfer near the Liouvillian exceptional point
Huixia Gao, Konghao Sun, Dengke Qu +4
As branch-point singularities of non-Hermitian matrices, the exceptional points (EPs) exhibit unique spectral topology and criticality, with intriguing dynamic consequences in non-…
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…
Microwave control of collective quantum jump statistics of a dissipative Rydberg gas
Zong-Kai Liu, Kong-Hao Sun, Albert Cabot +12
Quantum many-body systems near phase transitions respond collectively to externally applied perturbations. We explore this phenomenon in a laser-driven dissipative Rydberg gas that…
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…
Chiral state transfer under dephasing
Konghao Sun, Wei Yi
Exceptional points emerge in the complex eigenspecra of non-Hermitian systems, and give rise to rich critical behaviors. An outstanding example is the chiral state transfer, where…
