Ultrafast quantum dynamics and photonics

Our scientific focus is set on ultrafast phenomena dominating the physics of solids, molecules and custom tailored nanostructures. We aim to understand and control the microscopic interplay between elementary degrees of freedom and exploit this knowledge to design quantum systems with novel functionalities. As the essential tool box, we conceive highly intense sources of ultrashort phase-locked laser pulses as well as field-sensitive detectors for the entire infrared and terahertz window of the electromagnetic spectrum. Similarly to an extreme slow motion camera, this technology allows us to capture and control elementary quantum dynamics on the femtosecond scale (1 fs = 10-15 s). In particular, the availability of record-intense and ultrashort electric and magnetic field transients allows us to study matter under unprecedented high-field conditions and reach an extremely non-adiabatic limit of light-matter interaction. Exciting new pathways to quantum electronics, quantum optics and quantum electrodynamics have been opened.

Our current list of projects includes:
  • Ultrastrong and non-adiabatic light-matter coupling
  • Quantum electronics of strongly correlated materials
  • Terahertz nonlinear optics
  • Femtosecond photonics
