Abstract
Recent nonlinear optical experiments have revealed novel signals of conferred chirality arising from achiral molecules in the vicinity of a chiral nanostructure. Hyper-Raman signals associated with molecular vibrations of the molecules display significantly different levels of intensity when the pump radiation is switched between left- and right-handed circular polarization. Here, a detailed quantum electrodynamical theory is presented to account for the operative mechanism in such systems, providing a comprehensive analysis of the phenomenon. Despite the analytical complexity, it is shown that in specific cases of application the results can support experiments with simple, tractable formalism.
