Clustering Theorem for Bose-Hubbard class Gibbs states
Xin-Hai Tong, Tomotaka Kuwahara, Zongping Gong
We establish the exponential clustering of correlation functions for the high-temperature Gibbs states of Bose-Hubbard type models. To overcome the technical difficulties arising f…

Scattering States in One-Dimensional Non-Hermitian Baths
Jimin Li, Yuwen E. Zhang, Franco Nori +1
A single quantum emitter coupled to a structured non-Hermitian environment shows anomalous bound states and real-time dynamics without Hermitian counterparts, as shown in [Gong et…

Waveguide QED with dissipative light-matter couplings
Xing-Liang Dong, Peng-Bo Li, Zongping Gong +1
Dissipative light-matter coupling plays a vital role in non-Hermitian physics, but it remains largely unexplored in waveguide QED systems. In this work, we find that by employing p…
