Coherent Population Trapping with Controlled Interparticle Interactions
H. Schempp, G. Günter, C. S. Hofmann +7
We investigate Coherent Population Trapping in a strongly interacting ultracold Rydberg gas. Despite the strong van der Waals interactions and interparticle correlations, we observ…
Evidence of antiblockade in an ultracold Rydberg gas
Thomas Amthor, Christian Giese, Christoph S. Hofmann +1
We present the experimental observation of the antiblockade in an ultracold Rydberg gas recently proposed by Ates et al. [Phys. Rev. Lett. 98, 023002 (2007)]. Our approach allows t…
Autoionization of an ultracold Rydberg gas through resonant dipole coupling
T. Amthor, J. Denskat, C. Giese +4
We investigate a possible mechanism for the autoionization of ultracold Rydberg gases, based on the resonant coupling of Rydberg pair states to the ionization continuum. Unlike an…
Rabi oscillations between ground and Rydberg states and van der Waals blockade in a mesoscopic frozen Rydberg gas
Markus Reetz-Lamour, Johannes Deiglmayr, Thomas Amthor +1
We present a detailed analysis of our recent observation of synchronous Rabi oscillations between the electronic ground state and Rydberg states in a mesoscopic ensemble containing…
Rabi oscillations and excitation trapping in the coherent excitation of a mesoscopic frozen Rydberg gas
Markus Reetz-Lamour, Thomas Amthor, Johannes Deiglmayr +1
We demonstrate the coherent excitation of a mesoscopic ensemble of about 100 ultracold atoms to Rydberg states by driving Rabi oscillations from the atomic ground state. We employ…
Modeling many-particle mechanical effects of an interacting Rydberg gas
Thomas Amthor, Markus Reetz-Lamour, Christian Giese +1
In a recent work [Phys. Rev. Lett. 98, 023004 (2007)] we have investigated the influence of attractive van der Waals interaction on the pair distribution and Penning ionization dyn…
