Titulo: Light-matter coupling in solid state cavity quantum electrodynamics: from the weak to the ultrastrong coupling and beyond
Resumen: Cavity quantum electrodynamics studies the interaction of light and matter in confined geometries. Improvements both in the photonic confinement and in the emitter design of solid state implementations have led to a steady increase in the strength of the observed light-matter coupling [1,2]. This has allowed us to access interaction-dominated regimes, in which many fascinating non-perturbative physical phenomena become observable: from quantum vacuum radiation to quantum phase transitions. After a general introduction to light-matter coupling and cavity quantum electrodynamics [3,4], I will introduce some of these fascinating phenomena and I will give an overview of the experimental efforts that are been conducted to observe them.
