Anomalous Motion of Particle Levitated by Laguerre-Gaussian beam
Yang Li, Lei-Ming Zhou, Nan Zhao
Laguerre-Gaussian (LG) beam has orbital angular momentum (OAM). A particle trapped in an LG beam will rotate about the beam axis, due to the transfer of OAM. The rotation of the pa…

Robust optical-levitation-based metrology of nanoparticle's position and mass
Yu Zheng, Lei-Ming Zhou, Yang Dong +4
Light has shown up an incredibe capability in precision measurement based on opto-mechanic interaction in high vacuum by isolating environment noises. However, there are still obst…
