Abstract
Optical binding in liquid and in vacuum continues to unveil and enable new physics. We present two results. Firstly, we show how, for particles beyond the Rayleigh limit, surprising asymmetric forces can arise in counter-propagating beams. These can cause particle transport or instability. Secondly, we show how optical binding between two microspheres levitated in vacuum can be used for sympathetic cooling of the centre of mass motions of the spheres to sub-Kelvin temperatures.
