Direct Measurement of the van der Waals Interaction between Two Rydberg Atoms
Direct Measurement of the van der Waals Interaction between Two Rydberg Atoms
We report on the direct measurement of the van der Waals interaction between two isolated, single Rydberg atoms separated by a controlled distance of a few micrometers. By working in a regime where the single-atom Rabi frequency of the laser used for excitation to the Rydberg state is comparable to …
