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…
