Single-atom sensor for low-frequency electric field
Quan Yuan, Shuang-Qing Dai, Tai-Hao Cui +8
Precision measurement of low-frequency electric field (LFEF) signals with frequency from 30 kHz to 300 kHz is crucial for advancing both fundamental science and practical applicati…
Enhanced detection of electric field signals via squeezing-induced stochastic resonance
Ya-Qi Wei, Tai-Hao Cui, Quan Yuan +10
Stochastic resonance (SR) could amplify weak electric-field signals in nonlinear systems by means of the externally injected noises. Here we propose and experimentally demonstrate…
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…
Detection of DC electric forces with zeptonewton sensitivity by single-ion phonon laser
Ya-Qi Wei, Ying-Zheng Wang, Zhi-Chao Liu +6
Detecting extremely small forces helps exploring new physics quantitatively. Here we demonstrate that the phonon laser made of a single trapped Ca ion behaves as an ex…
