Universal scaling in a strongly interacting Rydberg gas
Robert Löw, Hendrik Weimer, Ulrich Krohn +5
We study a gas of ultracold atoms resonantly driven into a strongly interacting Rydberg state. The long distance behavior of the spatially frozen effective pseudospin system is det…
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…
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…
