Quantum Chemistry Meets Quantum Electrodynamics: Molecule-Cavity Interaction Simulation

Simulating interactions between molecules coupled to an optical cavity is possible with a new model that combines quantum electrodynamics and a widely used formalism from quantum chemistry. Markus Kowalewski is associate Professor at Fysikum and is responsible for the research group Molecular Quantum Dynamics and Spectroscopy (TQDSpec).

Mapping molecular funnels with X-rays: precise timings of non-adiabatic excited state dynamics

Time-resolved spectroscopy is a tool that provides access to the time-scale of chemical reactions as they happen. With the help of ultra-short light pulses, it is possible to observe conformal changes in molecules on the time-scale of the atomic motion and electronic motion. Photochemical reactions, such as the damage of DNA by means of sunlight or the key-step in the process of vision, can thus be observed in great detail.
