Hamburg Photon Science Colloquium | Microscopy with a twist - exploring reciprocal space by tunneling

by Felix von Oppen (Freie Universität Berlin, Germany)

Friday 13 Dec 2024, 14:00 → 15:30 Europe/Berlin

SemR I-III (CFEL, Bldg. 99)

Twisted bilayer graphene opened a new world of engineered quantum materials and quantum phases of matter. The recently developed quantum twisting microscope (QTM) leverages these developments for a new tunneling probe of van der Waals materials, combining spatial resolution with direct access to reciprocal space. This talk will discuss this exciting new technique from a theoretical perspective, including elastic and inelastic spectroscopy of electron and collective-mode dispersions.

Coffee, tea and cake will be served at 1:45 pm.
