The Role of Chirality and Hyperbolicity in Light-Matter Interaction

Giuseppe Strangi, PhD, Professor of Physics and Ohio Research Scholar, Department of Physics, Case Western Reserve University

Presented in-person in Goergen 101 and on Zoom

Abstract

Hyperbolic dispersion metasurfaces enabled, among many other phenomena, the diverging of photonic density of states and anomalous wave propagation, which have demonstrated to have a profound impact at the intersection of classical and quantum optics. This talk will review how we inverse design and engineer metasurfaces that support hyperbolic dispersion and chiral polarizability. The fundamental focus of this work remains the control of extreme light-matter interaction stemming from these physical properties, by harnessing excitonic physics, strongly correlated phenomena and light-induced forces in optomechanics.
