    "abstract": "The time dependence of nonclassical correlations is investigated for two\nfields (1,2) generated by an ensemble of cold Cesium atoms via the protocol of\nDuan et al. [Nature Vol. 414, p. 413 (2001)]. The correlation function R(t1,t2)\nfor the ratio of cross to auto-correlations for the (1,2) fields at times\n(t1,t2) is found to have a maximum value Rmax=292(+-)57, which significantly\nviolates the Cauchy-Schwarz inequality R\u003c=1 for classical fields. Decoherence\nof quantum correlations is observed over 175 ns, and is described by our model,\nas is a new scheme to mitigate this effect.",
