Understanding thermal induced escape mechanism of optically levitated sphere in vacuum
Mengzhu Hu, Nan Li, Zhenhai Fu +3
The escape phenomenon, mainly caused by thermal effects, is known as an obstacle to the further practical application of optical levitation system in vacuum. Irregular photophoresi…
Displacement calibration of optical tweezers with absolute gravitational acceleration
Jianyu Yang, Nan Li, Xunmin Zhu +5
In recent years, levitated particles of optical traps in vacuum have shown enormous potential in precision sensor development and searching for new physics. The accuracy of the cal…
Maltese cross coupling to individual cold atoms in free space
Natalia Bruno, Lorena C. Bianchet, Nan Li +3
We report on the simultaneous observation from four directions of the fluorescence of single Rb atoms trapped at the common focus of four high numerical aperture (${\rm NA}=…
Launch and capture of a single particle in a pulse-laser-assisted dual-beam fiber-optic trap
Zhenhai Fu, Xuan She, Nan Li +1
The rapid loading and manipulation of microspheres in optical trap is important for its applications in optomechanics and precision force sensing. We investigate the microsphere be…
