    "abstract": "We analyze the evolution of a quantum Brownian particle starting from an\ninitial state that contains correlations between this system and its\nenvironment. Using a path integral approach, we obtain a master equation for\nthe reduced density matrix of the system finding relatively simple expressions\nfor its time dependent coefficients. We examine the evolution of delocalized\ninitial states (Schr\\\"odinger\u0027s cats) investigating the effectiveness of the\ndecoherence process. Analytic results are obtained for an ohmic environment\n(Drude\u0027s model) at zero temperature.",
