dr Katarzyna Kluczyk-Korch (IGF UW)Plasmons in bimetallic nanoparticles: How does the atomic structure affect plasmons and their coupling with molecules?
We study core-shell bimetallic nanoparticles using the first-principles approach to understand how the arrangement of the metallic domains affects their plasmonic features. Our research investigates changes in the position of plasmonic resonances, strength, distribution of the electromagnetic field, and generation of hot carriers. We design a nanoparticle with two separate plasmonic resonances and demonstrate that it can be strongly coupled with two distinct molecules. As a case of study, we chose Na/Mg nanoparticles in core-shell geometry and benzene derivatives as molecules.

prof. Kestutis Staliunas (Universitat Politècnica de Catalunya, UPC)Nohermitian light trapping in micro modulated thin films
One of the exceptional features of non-Hermitian systems is the unidirectional wave interactions. At a particular (exceptional) point the situation can be achieved, that the external radiation is efficiently coupled into the system, but the internal radiation cannot escape backwards. We realize this idea in non-Hermitically modulated thin films, consisting of a Hermitian part - the periodic corrugation of the surfaces of a film, and a non-Hermitian part - the modulation of losses along the film. We prove numerically and demonstrate experimentally that the incident radiation, coupled with such a non-Hermitian thin film, is unidirectionally trapped into a planar mode of the film, does not escape from the film (or escape weakly due to experimental imperfections), and is efficiently absorbed there.
