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…
Thermalization of Quantum Many-Body Scars in Kinetically Constrained Systems
Jia-wei Wang, Xiang-Fa Zhou, Guang-Can Guo +1
The phenomenon of quantum many-body scars (QMBS) has been studied both theoretically and experimentally, due to its unusual violation of the eigenstate thermalization hypothesis (E…
Super-Heisenberg scaling in a triple point criticality
Jia-Ming Cheng, Yong-Chang Zhang, Xiang-Fa Zhou +1
We investigate quantum-enhanced metrology in a triple point criticality and discover that quantum criticality can not always enhance measuring precision. We have developed suitable…
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…
