    "abstract": "A quantum-mechanical Gaussian wave-packet approach to the theoretical\ndescription of nuclear motions in a condensed-phase environment is developed.\nGeneral expressions for the time-dependent reduced density matrix are given for\na harmonic potential surface, and the exact quantum dynamics is found for a\nmicroscopic system-plus-bath model. Particular attention is devoted to the\ninfluence of initial correlations between system and bath for the outcome of a\npump-probe experiment. We show that the standard factorized preparation,\ncompared to a more realistic correlated preparation, leads to significantly\ndifferent stimulated emission spectra at high temperatures. Recent experiments\nfor the reaction center are analyzed using this formalism.",
