Green's functions: a powerful tool to enhance the ultraviolet response of nanostructures Seminar

Event details

We develop an analytic decomposition of the electromagnetic Green's functions in terms of continuous spectra of plane waves and discrete sets of electromagnetic modes and determine the response of several complex nanostructures in the ultraviolet. Our approach is very general and can be applied to any quantum or classical process that involves the electromagnetic linear response of a complex nanostructure, even in the presence of strong losses. We find that combining nano-antennae with substrates, is possible to alter the properties of the quantum vacuum in the ultraviolet to simultaneously enhance the spontaneous transition rates and the far field emission of quantum emitters. This opens the way to the detection of weakly fluorescent organic molecules and nano lasing.
