On Monday, November 10, 2025, at 12:00 c.t., our next physics colloquium will take place. Prof. Dr. Philip Moll, Director of the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg will give a talk on "Quantum Materials on the Mesoscale".
Quantum materials encompass central themes of interacting electron physics and topology which promise a wealth of unconventional electronic responses and functionality. These topics combined high Tc superconductors, strongly correlated electron systems, topologically non-trivial metals and unconventional magnetic materials - generally such systems in which quantum mechanics manifests in unusual ways due to interactions and frustration. These materials are researched immensely in bulk crystals (3D) and thin films (2D), including both epitaxy and van der Waals stacking. The region between these limits presents an underexplored field of rich physics on the mesoscale, commonly for 3D structures in the 10-0.1mm size range. Here, confined geometries become important for collective phenomena without quantizing the single-particle momenta yet. Designing the vessel for the interacting liquid has remarkable responses on their responses. I will review recent technological advances in Focused Ion Beam based shaping of single crystals, and discuss the physics of microscopically shaped Kagome metals, semi-metals in the quantum limit and geometrically tailored vortex matter.
