Topological Edge Plasmons in Quantum Many-Body Systems

Seminar Link: Picoelectrodynamics Theory Network - YouTube Abstract We discuss how the many-body excitation spectrum of topological insulators is affected by the presence of long-range Coulomb interactions. In the one-dimensional Su-Schrieffer-Heeger model and its mirror-symmetric variant, strongly...

A Dual Perspective On Inverse Design

Seminar Link: Picoelectrodynamics Theory Network - YouTube Abstract For a wide range of technologically prescient applications---spanning from achieving low-power nonlinear response to mode-multiplexing in optical communication---device architectures discovered via computational methods increasingly...
