- We present the results of experimental studies of the propagation of light pulses through a specially prepared atomic medium with steep anomalous dispersion and enhanced Kerr nonlinearity. The observed negative group velocity is consistent with the principle of causality. The long-lived bright Zeeman coherence that is responsible for the steep anomalous dispersion gives rise also to a giant nonlinearity of the atomic susceptibility, which contributes substantially to the pulse propagation process. The enhanced atomic Kerr nonlinearity in the bright coherent state has been estimated.
