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. A central focus is to create a platform for junior researchers through integrated poster sessions and networking events. The event will be held at the Krähennest in Hamburg and include an excursion to the Max Planck Institute for the Structure and Dynamics of Matter, showcasing experimental advances in 3D quantum materials.
The conference language will be English. The Wilhelm and Else Heraeus-Foundation bears the cost of full-board accommodation for all participants.
