Abstract

Optical binding can be understood as a laser perturbation of intermolecular forces. Applying state-of-the-art QED theory, it is shown how light can move, twist and create ordered arrays from molecules and nanoparticles. The dependence on laser intensity, geometry and polarization are explored, and intricate potential energy landscapes are exhibited. A detailed exploration of the available degrees of geometric freedom reveals unexpected patterns of local force and torque. Numerous positions of local potential minimum and maximum can be located, and mapped on contour diagrams. Islands of stability and other structures are then identified.
