    "abstract": "We propose a scheme to generate double electromagnetically induced\ntransparency and optimal cross-phase modulation for two slow, copropagating\npulses with matched group velocities in a single species of atom, namely 87 Rb.\nA single pump laser is employed and a homogeneous magnetic field is utilized to\navoid cancellation effects through the nonlinear Zeeman effect. We suggest a\nfeasible preparational procedure for the atomic initial state to achieve\nmatched group velocities for both signal fields.",
