Observation of Rydberg Blockade Induced by a Single Ion
Felix Engel, Thomas Dieterle, Thomas Schmid +6
We study the long-range interaction of a single ion with a highly excited ultracold Rydberg atom and report on the direct observation of ion-induced Rydberg excitation blockade med…

An ionic impurity in a Bose-Einstein condensate at sub-microkelvin temperatures
Kathrin S. Kleinbach, Felix Engel, Thomas Dieterle +3
Rydberg atoms immersed in a Bose-Einstein condensate interact with the quantum gas via electron-atom and ion-atom interaction. To suppress the typically dominant electron-neutral i…
