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…
A planar multipole ion trap
M. Debatin, M. Kröner, J. Mikosch +6
We report on the realisation of a chip-based multipole ion trap manufactured using micro-electromechanical systems (MEMS) technology. It provides ion confinement in an almost field…
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…
Mechanical effect of van der Waals interactions observed in real time in an ultracold Rydberg gas
T. Amthor, M. Reetz-Lamour, S. Westermann +2
We present time-resolved spectroscopic measurements of Rydberg-Rydberg interactions in an ultracold gas, revealing the pair dynamics induced by long-range van der Waals interaction…
Suppression of Excitation and Spectral Broadening Induced by Interactions in a Cold Gas of Rydberg Atoms
Kilian Singer, Markus Reetz-Lamour, Thomas Amthor +2
We report on the observation of ultralong range interactions in a gas of cold Rubidium Rydberg atoms. The van-der-Waals interaction between a pair of Rydberg atoms separated as far…
