A Single-Particle Diagnosis of an Interacting Topological Insulator
Theo N. Dionne, Maia G. Vergniory
Understanding how topology survives in strongly correlated systems remains a central challenge, as most topological diagnostics rely on non-interacting band structures. Here we pre…

Characterizing Mott Insulators in the Interacting One-Body Picture
Theo N. Dionne, Santiago Villodre, Mikel Iraola +1
The one-body picture underlies our understanding of weakly interacting solids but breaks down in strongly correlated systems. We develop a general framework, based on the single-pa…

Nonlinear longitudinal current of band-geometric origin in wires of finite thickness
Robin Durand, Louis-Thomas Gendron, Théo Nathaniel Dionne +1
The miniaturization of integrated circuits is facing an obstruction due to the escalating electrical resistivity of conventional copper interconnects. The underlying reason for thi…
