报告人：吴紫辉副研究员（Dr. Jack Ng，Department of Physics and Institute of Computational and Theoretical Studies，Hong Kong Baptist University)
As small particleswill migrate to the high laser intensity region to minimize the free energy,one can trap and manipulate small particles at will with a focused laser. This optical manipulation technique has applications range from the trapping and cooling of atoms, to large molecules, and to microscopic particles and biological objects.
I will briefly introduceour progresses on the theory and modeling of optical micromanipulation – the manipulation of micron-sized objects. I intend to cover all or some of the following topics,where, in addition to the theoretical predictions, their experimental implementation will also be briefly discussed.
Someexperimental and theoretical progress in optical binding (the use of light to bind particles into a single entity) will be reporte.
