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…
Laser frequency stabilization to highly excited state transitions using electromagnetically induced transparency in a cascade system
R. P. Abel, A. K. Mohapatra, M. G. Bason +4
We demonstrate laser frequency stabilization to excited state transitions using cascade electromagnetically induced transparency (EIT). Using a room temperature Rb vapor cell as 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…
Apparatus for excitation and detection of Rydberg atoms in quantum gases
Robert Loew, Ulrich Raitzsch, Rolf Heidemann +4
We present and characterize a versatile experimental setup which allows for excitation and detection of Rydberg atoms in quantum gases. The novel concept of the setup features two…
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…
