英文摘要	based on the hubbard-stratonovich transformation, the dissipative interaction between the system of interest and the heat bath is decoupled and the separated system and bath thus evolve in common classical random fields. this manipulation allows us to establish a novel theoretical methodology by which the reduced density matrix is formulated as an ensemble average of its random realizations in the auxiliary white noise fields. within the stochastic description, the interaction between the system and the bath is reflected in the mutually induced mean fields. the relationship between the bath-induced field and the influence functional in the path integral framework is revealed. as a demonstration of this approach, we derive the exact master. equations for two model systems.
