Paper Abstract

We present a few of our recent theoretical and experimental results related to the behavior of micron-scale particles placed into nonlinear optical potentials. The two-dimensional optical ratchet can rectify motion of Brownian particles in any direction in the plane and unstable cubic optical potential results in noise-induced particle motion. Action of optical spin-force was demonstrated in a novel geometry where it is responsible for particle orbiting.
