Phys. Rev. Lett. 95, 253002 (2005) [4 pages]Atom Counting Statistics in Ensembles of Interacting Rydberg AtomsSee Also: Erratum Received 26 July 2005; published 13 December 2005 We show that the probability distributions for the number of Rydberg excitations in small ensembles of cold atoms, excited using short (100 ns) laser pulses, can be highly sub-Poissonian. The phenomenon occurs if the atom density and the principal quantum number of the excited Rydberg level are sufficiently high. Our observations are attributed to a blockade of the Rydberg atom excitation. © 2005 The American Physical Society URL:
