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…
