Seminar Link: Picoelectrodynamics Theory Network - YouTube Abstract The discovery of topological materials is one of the most transformative recent breakthroughs in condensed matter physics, revealing new conceptual surprises in established topics such as the phases of matter and the behavior of...

Seminar Link: Picoelectrodynamics Theory Network - YouTube Abstract Over the past three decades, graphene has become the prototypical platform for discovering topological phases of matter. Both the Chern C∈Z and quantum spin Hall υ∈Z2 insulators were first predicted in graphene, which led to a...

Seminar Link: Picoelectrodynamics Theory Network - YouTube A Contemporary View On Topological Band Theory & New Euler Class Phenomena In this talk, I will cover a selection of our recent work on topological characterizations in a rather colloquial style. In particular, I will review how constraints...

Seminar Link: Picoelectrodynamics Theory Network - YouTube Microscopic polarization and magnetization fields: Towards a “post-modern” theory The response of solids to incident electromagnetic fields is often heuristically described in terms of macroscopic polarization and magnetization fields. In...

Seminar Link: Picoelectrodynamics Theory Network - YouTube Abstract Hyperbolic lattices are a new form of synthetic quantum matter in which particles effectively hop on a discrete tiling of two-dimensional hyperbolic space, a non-Euclidean space of negative curvature. Hyperbolic tilings were studied...

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...

Singular evanescent wave resonances in moving media Resonators fold the path of light by reflections leading to a phase balance and thus constructive addition of propagating waves. However, the amplitude decrease of these waves due to incomplete reflection or material absorption leads to a finite...
