Abstract
By means of the extended discrete dipole approximation into which the microscopic nonlocal response is incorporated, we theoretically demonstrate the radiation force and torque exerted on single molecules near the metallic nanogap. In this theory, we consider the spatial interplay between the light electric field localized within a nanometer-sized region and molecular wavefunctions. The results show a strong enhancement of exerted force due to the plasmonic and electronic double resonances, and also show the possibility of selective control of molecular alignment and orientation near the nanogap by the resonance laser manipulation.
