Investigation of dephasing rates in an interacting Rydberg gas
U. Raitzsch, R. Heidemann, H. Weimer +6
We experimentally and theoretically investigate the dephasing rates of the coherent evolution of a resonantly driven pseudo spin emersed in a reservoir of pseudo spins. The pseudo…
Novel binding mechanism for ultra-long range molecules
V. Bendkowsky, B. Butscher, J. Nipper +3
Molecular bonds can be divided into four primary types: ionic, covalent, van der Waals and hydrogen bonds. At ultralow temperatures a novel binding type emerges paving the way for…
Giant electro-optic effect using polarizable dark states
A. K. Mohapatra, M. G. Bason, B. Butscher +2
The electro-optic effect, where the refractive index of a medium is modified by an electric field, is of central importance in non-linear optics, laser technology, quantum optics a…
Rydberg excitation of Bose-Einstein condensates
Rolf Heidemann, Ulrich Raitzsch, Vera Bendkowsky +3
Rydberg atoms provide a wide range of possibilities to tailor interactions in a quantum gas. Here we report on Rydberg excitation of Bose-Einstein condensed 87Rb atoms. The Rydberg…
An echo experiment in a strongly interacting Rydberg gas
Ulrich Raitzsch, Vera Bendkowsky, Rolf Heidemann +3
When ground state atoms are excited to a Rydberg state, van der Waals interactions among them can lead to a strong suppression of the excitation. Despite the strong interactions th…
Evidence for coherent collective Rydberg excitation in the strong blockade regime
Rolf Heidemann, Ulrich Raitzsch, Vera Bendkowsky +4
Blockade effects on the single quantum level are at the heart of quantum devices like single-electron transistors. The blockade mechanisms are based on strong interactions like the…
