    "abstract": "We study the propagation of a quantum probe light in an ensemble of\n\"3+1\"-level atoms when the atoms are coupled to two other classical control\nfields. First we calculate the dispersion properties, such as susceptibility\nand group velocity, of the probe light within such an atomic medium under the\ncase of three-photon resonance via the dynamical algebra method of collective\natomic excitations. Then we calculate the dispersion of the probe light not\nonly under the case that two classical control fields have the same detunings\nto the relative atomic transitions but also under the case that they have the\ndifferent detunings. Our results show in both cases the phenomenon of\nelectromagnetically induced transparency can accur. Especially use the second\ncase, we can find two transparency windows for the probe light.",
