Collective-motion-enhanced acceleration sensing via an optically levitated microsphere array
Yao Li, Chuang Li, Jiandong Zhang +2
Optically levitated microspheres are an excellent candidate for force and acceleration sensing. Here, we propose an acceleration sensing protocol based on an optically levitated mi…

Realization of all-optical underdamped stochastic Stirling engine
Chuang Li, Shaochong Zhu, Peitong He +6
We experimentally demonstrate a nano-scale stochastic Stirling heat engine operating in the underdamped regime. The setup involves an optically levitated silica particle that is su…
