Topological Mott Insulators: Green's Function Zeros and Boundary Effects

Explore a 43-minute symposium talk that delves into a novel approach to understanding topological Mott insulators through the analysis of single-particle Green's function zeros and their momentum dispersion. Learn how the bulk-boundary correspondence manifests in these systems and discover a proposed method for understanding boundary zeros through their interaction with topologically protected edge modes. Gain insights into the challenges of classifying topological Mott insulators due to their complex many-body nature, and understand how this new perspective offers a simpler framework for describing these quantum systems.
