Quantum dynamics of atomic and molecular systems
Our group studies atomic and molecular quantum systems with respect to their interactions on different levels of complexity. Of special importance is the application and extension of modern methods for the manipulation and quantum control to many-body quantum systems, in particular using coherent light. The systems under investigation range from highly excited Rydberg atoms over atomic and molecular quantum gases to molecular aggregates. The group develops technologies for trapping and cooling of neutral atoms as well as quantum-state sensitive diagnostics.

|Nonlinear optical response in Rydberg-EIT medium: paper published in Phys. Rev. A||06.12.2019|
This month, our paper on a "Blockade-induced resonant enhancement of the optical nonlinearity in a Rydberg medium" got published in Phys. Rev. A! We predict the enhancement of the nonlinear optical response of the Rydberg gas as a consequence of a two-photon process that resonantly couples electronic states of a pair of atoms dressed by a strong control field. Moreover, we propose a realistic experimental scenario to observe the resonance by performing transmission measurements

|Observation of dipolar splittings of Li-6 p-wave Feshbach resonances: paper published in Phys. Rev. A (Rapid Comm.)||11.11.2019|
Our paper on the "Observation of dipolar splittings in high-resolution atom-loss spectroscopy of Li-6 p-wave Feshbach resonances" got published this month in Phys. Rev. A Rapid Communications! We observed dipolar splitting in Li-6 p-wave Feshbach resonances by high-resolution atom-loss spectroscopy. The observed splittings are in very well agreement with coupled-channel calculations.
