"Imaging molecules with light using multiparticle coincidence detection"
Prof. Dr. Reinhard Dörner
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

|Dr. Clément Hainaut is now an Alexander von Humboldt Fellow||28.02.2019|
Congratulations to Clément Hainaut who was awarded an Alexander von Humboldt Fellowship! Clément joined the Rydberg team as a postdoc for investigating relaxation dynamics of Rydberg spin systems as well as nonlinear photon interactions in a Rydberg EIT medium!
|Annika Tebben receives Otto-Haxel-Prize for her Master thesis||27.10.2018|
During her Master thesis Annika Tebben investigated the nonlinear optical response of an interacting Rydberg gas under conditions of electromagnetically induced transparency. In collaboration with the group of Thomas Pohl (Aarhus) she found a method to resonantly enhance the associated nonlinear susceptibility. For her outstanding work Annika was awarded the Otto-Haxel-Prize of the department of physics and astronomy of Heidelberg University. Congratulations!
