@article{2009-khudaverdyan-meschede-phys-rev-lett-v103-p123006, Abstract = {We experimentally investigate the spin dynamics of one and two neutral atoms strongly coupled to a high finesse optical cavity. We observe quantum jumps between hyperfine ground states of a single atom. The interaction-induced normal-mode splitting of the atom-cavity system is measured via the atomic excitation. Moreover, we observe the mutual influence of two atoms simultaneously coupled to the cavity mode.}, Author = {Khudaverdyan, M. AND Alt, W. AND Kampschulte, T. AND Reick, S. AND Thobe, A.
