Max Planck Research Group "Ultrafast Solid State Spectroscopy"

The Ultrafast Solid State Spectroscopy group is a joint Research Group of the Max Planck Institute for Solid State Research and the Department of Physics at the University of Stuttgart. The research interest is ultrafast spectroscopy of strongly correlated electron materials, and novel quantum materials. The group applies advanced nonlinear optical methods such as ultra-broad band pump-probe spectroscopy, not only to investigate ultrafast dynamics in complex solid-state materials, but also to control them with light. Combining these methods with high-resolution optical near-field microscopy we can access such dynamics even with sub-wavelength resolution down to the nanoscale. One research focus is the light induced superconductivity in high-temperature superconductors. We investigate different scenarios like the balancing between competing phases triggered by ultrashort light pulses or explore possibilities of dynamical stabilization in periodically driven light fields. The latter relates directly to another main research field of the group − quantum many body dynamics in correlated electron materials. We use advanced quantum materials, e.g. organic conductors and superconductors, as model systems to investigate the ultrafast dynamics of electronic correlations and their coupling to external excitations. We aim tracing the dynamics of the system directly on the time-scale of the effective electronic interactions. In order to control such systems we use mode selective driving of local (molecular) vibrations that allows us modulating the effective interactions and induce quantum quenches in solid state Mott systems.
