Présentation

**Scientific interests** ======================== **In general, I am mostly interested in the study of elementary excitations and particles (electrons, magnons, phonons, photons, plasmons, etc.), their interactions and their role in the onset of collective and macroscopic states that underpin the observed phenomena.** **My present focus is on electrodynamics of hybrid nanostructures and the study of efficient channels for energy absorption, conversion and transfer.** **Position held & Institution** =================================== Professeur des universités (Theoretical Physics) Systèmes et Structures Nanométriques : propriétés optiques, électroniques et magnétiques (S2N-POEM) Laboratoire PROMES - CNRS UPR8521 Universite de Perpignan Via Domitia (UPVD) Rambla de la Thermodynamique - Tecnosud 66100 Perpignan, France
