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…

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…
