Crossover from positive to negative optical torque in mesoscale optical matter

Negative optical torque has been predicted theoretically, but experimental demonstrations have been scarce. Here, the authors show that the optical torque in a mesoscopic optical matter array can be reversed depending on number, separation and configuration of nanoparticles in a circularly polarized...
