摘要
Electrodynamic interactions among nano-particle constituents of optical matter (OM) systems (in solution) formed in optical traps can exhibit dynamics arising from asymmetric center-of-mass forces and torques due to broken symmetry or through many body interactions. This talk will describe the origins of negative torque in 3-or more nano-particle OM arrays and the spin-to-orbital angular momentum conversion that drives the mechanical motion. The scattered fields can be exploited to create self-assembling optical matter machines. Understanding these systems and their dynamics requires close interaction of specialized electrodynamics-Langevin dynamics simulations with field strength and spatial phase that match the experimental conditions.
