Professor Kishan Dholakia, Professor of Physics at the University of St Andrews Scotland, will be giving a talk on 18th January.

Title: Let Nothing slow you down: optical manipulation in liquid, air and vacuum
Date: 18-01-2017
Time: 02:00 PM
Venue: ESB 244 Seminar Room (First Floor), Department of Electrical Engineering

Abstract
Optical manipulation of mesoscopic particles remains a very powerful method for both fundamental and applied science. The field has seen great advances for the biosciences including new studies of single molecules and force studies on cells. In the physical sciences, studies have also seen groundbreaking work in many areas. In this talk we describe some of the recent work at St Andrews looking particularly at the trapping of particles in liquid, air and vacuum with an emphasis on optical angular momentum transfer. By combining optical shaping of light with materials science new studies of viscosity and heating can be seen. In vacuum we observe rotation of one and two trapped particles and discuss prospects for studying effects at the classical-quantum interface
