    "abstract": "The majority of quantum open system models in the literature are simplistic\nin the sense that they only explicitly account for that part of the environment\nthat directly interacts with the system of interest. A quantum open system with\nan open environment is examined using the projection operator method in the\nweak coupling limit. The openness of environment is modelled by nonunitary\nevolution of the Lindblad form. Under certain conditions, the resulting master\nequation for the system is insensitive to the initial state of the environment\nand to initial entanglements between the system and environment for time scales\ngreater than the environment relaxation timescales. For the particular case of\nan environment consisting of a harmonic oscillator bath, the resulting master\nequations are demonstrated to have the algebraic form for completely positive\nevolution. The open environment model is illustrated for the particular case of\na system linearly coupled to an oscillator bath.",
