"Quantum effects in plasmonics" dr Ilya Razdolskiy, Katedra Fizyki Magnetyków, Wydział Fizyki, UwB

A rapidly developing branch of modern nanophotonics, plasmonics deals with optical properties of nanoscale objects capable of confining light in strongly subwavelength volumes. Despite its impressive body of knowledge and numerous applications in microscopy, chemistry, biology and medicine, its potential for the light-matter interaction at the nanoscale is often overlooked by solid-state physicists. In this talk, I will discuss plasmonic effects of essentially quantum nature beyond the conventional description based on Maxwell equations and Drude model, which can be of interest to the condensed matter community. In particular, we revisit the quantum properties of plasmon quasiparticles before moving on towards surface plasmon spectroscopy of ultrasmall nanosystems in the quantum regime. Lastly, I discuss the attempts to treat these effects as corrections to the classical description entailing nonlocality and Landau damping.
