Grand Canonical-like Thermalization of Quantum Many-body Scars
Jia-wei Wang, Xiang-Fa Zhou, Guang-Can Guo +1
Quantum many-body scar (QMBS) in kinetically constrained quantum systems challenges the conventional eigenstate thermalization hypothesis (ETH). We develop an effective open-system…
Enhancing analogue Unruh effect via superradiance in a cylindrical cavity
Hong-Tao Zheng, Xiang-Fa Zhou, Guang-Can Guo +1
We propose a scheme to detect the Unruh effect in a circularly rotated Unruh-DeWitt detector enclosed within a cylindrical cavity. This technique relies on the enhanced atomic spon…
Shortcuts to adiabatic state transfer in time-modulated two-level non-Hermitian systems
Qi-Cheng Wu, Jun-Long Zhao, Yan-Hui Zhou +4
Nontrivial spectral properties of non-Hermitian systems can give rise to intriguing effects that lack counterparts in Hermitian systems. For instance, when dynamically varying syst…
Narrowband telecom band polarization-entangled photon source by superposed monolithic cavities
Ming-Yuan Gao, Yin-Hai Li, Yan Li +4
A high-quality narrowband polarization-entangled source in the telecom band is preferred to avoid frequency dispersion for long-distance transmission in optical fibers and to effic…
