    "abstract": "In the laser excitation of ultracold atoms to Rydberg states, we observe a\ndramatic suppression caused by van der Waals interactions. This behavior is\ninterpreted as a local excitation blockade: Rydberg atoms strongly inhibit\nexcitation of their neighbors. We measure suppression, relative to isolated\natom excitation, by up to a factor of 6.4. The dependence of this suppression\non both laser irradiance and atomic density are in good agreement with a\nmean-field model. These results are an important step towards using ultracold\nRydberg atoms in quantum information processing.",
