    "abstract": "The interaction of a five-level atomic system involving electromagnetically\ninduced transparency with four light fields is investigated. Two different\nlight-atom configurations are considered, and their efficiency in generating\nlarge nonlinear cross-phase shifts compared. The dispersive properties of those\nschemes are analyzed in detail, and the conditions leading to group velocity\nmatching for two of the light fields identified. An analytical treatment based\non amplitude equations is used in order to obtain approximate solutions for the\nsusceptibilities, ehich are shown to fit well with the numerical simulations of\nthe full Bloch equations in a large parameter region.",
