• Abstract: Non-radiative energy transfer between a Rydberg atom and a polar molecule can be controlled by a DC electric field. Here we show how to exploit this control for state-resolved, non-destructive detection and spectroscopy of the molecules where the lineshape reflects the type of molecular transition. Using the example of ammonia, we identify the conditions for collision-mediated spectroscopy in terms of the required electric field strengths, relative velocities, and molecular densities. Rydberg atom-enabled spectroscopy is feasible with current experimental technology, providing a versatile detection method as basic building block for applications of polar molecules in quantum technologies and chemical reaction studies.

• Femtosecond Photophysics of Molecular Polaritons [0.0]
  Molecular polaritons are hybrid states of photonic and molecular character that form when molecules strongly interact with light. We focus on the collective aspects of strongly coupled molecular systems and how this pertains to the dynamical response of such systems. We discuss how the ultrafast time and spectral resolution make pump-probe spectroscopy an ideal tool to reveal the energy transfer pathways from polariton states to other molecular states of functional interest.
