Extreme confinement with hyperbolic cavities - a new platform for quantum light-matter interactions
Hanan Herzig Sheinfux, Bar-Ilan University,

Abstract: The general premise of nanophotonics involves shrinking light to the subwavelength nanometric scale. For example by compressing light into the tiny volume of a nanocavity light matter interactions is dramatically enhanced. Alternatively, by chaining multiple nanocavities together we can also manipulate polaritonic propagation properties extensively. In my talk, I will demonstrate a new class of polaritonic cavities, which can provide 3D confinement to volumes 8 orders of magnitude smaller than the volume of a vacuum photon, while still maintaining an appreciable quality factor (Q~100). This breaks away from the nanophotonics paradigm that deep subwavelength cavities always exhibit low quality factors (high absorption) and paves the way for exciting cavity quantum electrodynamics experiments.

Lunch will be provided following the talk.
