WE-Heraeus-Seminar — Topology and Geometry: Novel Concepts in 3D Quantum Transport on the Mesoscale

The Heraeus workshop “Topology and geometry: Novel concepts in 3D quantum transport on the mesoscale” explores charge transport in mesoscale systems where conventional Ohmic scaling breaks down. As device dimensions shrink and materials complexity grows, transport becomes governed by a rich interplay of geometry, topology, and many-body interactions. We aim to unify perspectives across three key areas: (1) topological transport shaped by quantum geometry and Berry curvature, (2) semiclassical and quantum transport under high magnetic fields, and (3) strongly correlated electron dynamics including hydrodynamic flow and quantum criticality. Particular emphasis is placed on identifying how disparate length scales—mean free path, magnetic length, and correlation length—conspire to shape transport in modern materials. The workshop will foster cross-disciplinary exchange between condensed matter physics, materials chemistry, and device theory.
