Statistics and dynamics in an optical vortex
BY -
Yael Roichman

Abstract:
When two identical particles are driven along a straight line by an identical force there are no attractions forces between them.
Surprisingly, when the same two particles are driven along a ring of light, with identical force, they attract and form a pair.
The pairing mechanism is a pure non-equilibrium phenomenon and is a result of symmetry breaking due to the path’s curvature.
We use experiment, simulation and theory to demonstrate and explain this effect.
We show that dynamic limit-cycles and structure emerge due to this pseudo-potential in many particle systems,
and demonstrate how they depend on temperature and trapping stiffness.
