The Collaborative Research Center TRR 227 "Ultrafast Spin Dynamics" will host a special colloquium within a kick-off meeting of the second funding period. The colloquium will run online via Webex and is open to all members of the physics departments of the Freie Universität Berlin and the Martin Luther University Halle-Wittenberg without any registration.

Webex link will be provided to all members of physics departments of both universities via personal e-mails.

Tony F. Heinz is Professor of Applied Physics and Photon Science at Stanford University and Associate Laboratory Director for Energy Sciences at the SLAC National Accelerator Laboratory.

Probing electrons and electron dynamics in 2D materials and heterostructures

Two-dimensional (2D) materials provide a fascinating platform to investigate electron interactions and dynamics. In addition to access to the valley/spin degree of freedom, 2D semiconductors are notable for their pronounced excitonic effects. We will describe some of the ensuing dynamics in these systems, both for isolated monolayers and for heterostructures that we create by stacking 2D layers upon one another.

In addition to more conventional optical measurements, we will report recent results of time- and angle-resolved photoemission spectroscopy (tr-ARPES). This approach allows us to image exciton structure and dynamics in directly momentum space and has provided new insights into interlayer excitons and their localization within moiré potentials.
