Kibble--Zurek Scaling in the Dicke Model at Mesoscopic Scales
Haowei Li, Hanteng Wang
The Dicke model is a paradigmatic setting for collective light-matter physics and the superradiant phase transition. Yet extracting the critical exponents is challenging at experim…
Tunable Memory Effect in Dissipative Strongly Correlated Quantum Systems
Haowei Li, Yu Chen, Hui Zhai
Strongly interacting quantum many-body systems subjected to non-Markovian dissipation pose a formidable challenge due to the interplay between strong correlation effects and memory…
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…
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…
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…
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…
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…
Many-body non-Hermitian skin effect under dynamic gauge coupling
Haowei Li, Haojie Wu, Wei Zheng +1
We study an atom-cavity hybrid system where fermionic atoms in a one-dimensional lattice are subject to a cavity-induced dynamic gauge potential. The gauge coupling leads to highly…
Dissipative two-dimensional Raman lattice
Haowei Li, Wei Yi
We show that a dissipative two-dimensional Raman lattice can be engineered in a two-component ultracold atomic gas, where the interplay of the two-dimensional spin-orbit coupling a…
Topology and its detection in a dissipative Aharonov-Bohm chain
Haowei Li, Wei Yi
In a recent experiment, a dissipative Aharaonov-Bohm (AB) chain was implemented in the momentum space of a Bose-Einstein condensate. Formed by a series of dissipative AB rings thre…
Quantum Criticality of Liquid-Gas Transition in a Binary Bose Mixture
Li He, Haowei Li, Wei Yi +1
Quantum liquid, in the form of a self-bound droplet, is stabilized by a subtle balance between the mean-field contribution and quantum fluctuations. While a liquid-gas transition i…
Observation of Non-Hermitian Skin Effect and Topology in Ultracold Atoms
Qian Liang, Dizhou Xie, Zhaoli Dong +5
The non-Hermitian skin effect (NHSE), the accumulation of eigen wavefunctions at boundaries of open systems, underlies a variety of exotic properties that defy conventional wisdom.…
Non-Hermitian skin effect in a spin-orbit-coupled Bose-Einstein condensate
Haowei Li, Xiaoling Cui, Wei Yi
We study a Bose-Einstein condensate of ultracold atoms subject to a non-Hermitian spin-orbit coupling, where the system acquires non-Hermitian skin effect under the interplay of sp…
Engineering Non-Hermitian Skin Effect with Band Topology in Ultracold Gases
Lihong Zhou, Haowei Li, Wei Yi +1
Non-Hermitian skin effect(NHSE) describes a unique non-Hermitian phenomenon that all eigen-modes are localized near the boundary, and has profound impact on a wide range of bulk pr…
Non-Hermitian Kibble-Zurek mechanism with tunable complexity in single-photon interferometry
Peng Xue, Lei Xiao, Dengke Qu +7
Non-Hermitian descriptions of quantum matter have seen impressive progress recently, with major advances in understanding central aspects such as their topological properties or th…
