ERC Synergy Grant for “Orbital Cinema”
Together with our partners, Stefan Tautz from Jülich, Ulrich Höfer from Marburg, and Peter Puschnig from Graz, we have been awarded an ERC Synergy Grant worth 11.3 million €. In a close collaboration of our groups we will take actual slow-motion movies of molecular orbitals during charge transfer processes, chemical reactions, and wave packet motion driven by lightwaves.

Together with the group of Mackillo Kira (Michigan), we use multi-terahertz light fields to force electron-hole pairs in semiconductors onto closed recollision paths. Attosecond clocking of these trajectories reveals how many-body correlations like strong Coulomb interactions modify the charge carrier dynamics. This novel concept offers a completely new access to exotic phase transitions and quantum dynamics important for future electronic and quantum-information technologies.
We congratulate Joshua Mornhinweg on winning the first prize of the best student paper award of the 2022 International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz) in Delft with his talk titled nonlinear subcycle dynamics of ultrastrong light-matter interaction. The prize honours original contributions to the conference from outstanding student attendees....

We studied the ultrafast dynamics of intersubband polaritons in the mid-infrared together with the groups of Raffaele Colombelli (Paris), Christoph Lange (Dortmund) and Iacopo Carusotto (Trento). Stimulated scattering occurs between these polaritons for resonant excitation, which we observe directly within the polaritonic bandstructure. This scattering mechanism could enable Bose-Einstein-condensates of intersubband polaritons for novel quantum computers and on-chip mid-infrared light sources.
