DESCRIPTION:[b]Speaker: N. Asger Mortensen [/b] [nl]\nPOLIMA – Center for 
 Polariton-driven Light-Matter Interactions [nl]\nDanish Institute for Adv
 anced Study [nl]\nUniversity of Southern Denmark [nl][nl]\n[b]Abstract:[/
 b][nl]\nPolaritons are hybrid particles – quasiparticles – that result fr
 om the strong interaction between light (photons) and matter (such as ele
 ctrons\, excitons or phonons). These quasiparticles exhibit mixed charact
 eristics\, combining features of both photons and elementary particles li
 ke electrons. Colloquially\, they constitute half-light-half-matter excit
 ations. The interaction between light and matter in polaritons leads to u
 nique physical properties and behaviors that are now also being explored 
 in sheets of atomically thin two-dimensional materials and in artificial 
 nanostructures. The electrodynamics of matter and optical phenomena are c
 ommonly explored within the framework of classical electrodynamics and se
 miclassical models for the interactions of light with matter. Materials a
 re commonly assumed homogenous\, and light-matter interactions are treate
 d in an intuitive local manner. The plasmonic response of metal nanostruc
 tures is one such example\, where the understanding of mesoscopic electro
 dynamics at metal surfaces is\, however\, becoming increasingly important
  for both fundamental developments in quantum plasmonics and potential ap
 plications in emerging light-based quantum technologies. The seminar will
  discuss recent examples of quantum nonlocal effects that emerge in surfa
 ce-polaritonic systems\, including metal surfaces\, 2D materials\, and co
 mbinations thereof. [nl]\n\n[b]Biography:[/b][nl] \nMortensen is a full p
 rofessor in the Center for Polariton-driven Light-Matter Interactions (PO
 LIMA) and a Chair of Physics in the Danish Institute for Advanced Study\,
  both at the University of Southern Denmark. Previously\, he held a full 
 professorship (faculty since 2004) at the Technical University of Denmark
  (DTU). In addition to his MSc (1998) and PhD (2001) degrees from DTU\, h
 e holds higher doctoral degrees from University of Copenhagen (Dr. Scient
 .\, 2021) and DTU (Dr. Tech.\, 2006). He is a fellow of APS\, OSA\, SPIE\
 , IOP\, and European Academy of Sciences. Currently\, he serves the AAAS 
 as an associate editor for Science Advances.\n[nl]\n[nl]
