Avec l'aide du GDR de Physique Quantique Mésoscopique et du GDR de Plasmonique Moléculaire et Spectroscopies Exaltées, nous organisons un atelier sur les modes chiraux en optique et électronique des systèmes bidimensionnels (2D) dans l'idée d'établir un dialogue entre ceux qui travaillent avec des électrons, des photons, des plasmons, des polaritons, des excitons, des paires de Cooper, des atomes froids, phonons, etc. Il y aura trois sessions: 1) optique, 2) électronique et 3) cristaux artificiels. Chaque session débutera par un exposé de revue (mini-cours).

Trois mini-cours d'introduction (1h30) aux modes chiraux:

- en optique: Kostya Bliokh (Riken, Japon/Canberra, Australie): Angular momenta and spin-orbit interactions of light

- en électronique: Pascal Simon (Orsay, France): Chiral edge states in topological insulators and superconductors

- avec des cristaux artificiels: Alberto Amo (Lille, France): Chiral modes in artificial crystals
