Finite-Time Electrometry with a Quantum-Regime Single-Ion Phonon Laser
Pei-Dong Li, Yuan-Zhang Dong, Zhuo-Zhu Wu +6
The phonon laser realized in a trapped ion, i.e., a self-sustained mechanical oscillator, has demonstrated the unique characteristics in practically detecting externally applied el…
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…
Experimental Witness of Quantum Jump Induced High-Order Liouvillian Exceptional Points
Zhuo-Zhu Wu, Pei-Dong Li, Tai-Hao Cui +11
The exceptional point has presented considerably interesting and counterintuitive phenomena associated with nonreciprocity, precision measurement, and topological dynamics. The Lio…
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…
Quantum Many-body Scar Models in One Dimensional Spin Chains
Jia-Wei Wang, Xiang-Fa Zhou, Guang-Can Guo +1
The phenomenon of quantum many-body scars has received widespread attention both in theoretical and experimental physics in recent years due to its unique physical properties. In t…
