"Quantum aspects of plasmons in graphene and other atomic-scale systems"

Abstract: Plasmons in atomic-scale structures exhibit intrinsic quantum phenomena related to both the finite confinement that they undergo and the small number of electrons on which they are supported. Their interaction with two-level emitters is also evidencing strong quantum effects. In this talk I will discuss recent results from my group on several salient features of plasmons in graphene and other atomic-scale materials, and in particular their ability to mediate ultrafast heat transfer, the generation of high harmonics, their interaction with molecules and quantum emitters, and their extreme nonlinearity down to the single-photon level.

Bio: Javier García de Abajo obtained his PhD in condensed matter theory from the University of the Basque Country (Spain) in 1993. After spending three years in Berkeley National Lab., he became staff scientist at CSIC (Spain) and he was promoted to Research Professor in 2008. He is currently leading the Nanophotonics Theory group at ICFO. He has worked in atomic collisions, surface science, electron microscope spectroscopies, plasmonics, and theoretical nanophotonics. He is a Fellow of both the American Physical Society and the Optical Society of America.
