英文摘要	as a system can be separated from its heat bath via a decoupling scheme based on the hubbard-stratonovich transformation, the quantum dissipative dynamics is exactly described by the average of the random system moving in the stochastic field induced by the bath. as a test of this stochastic formalism, a direct numerical implementation is employed to simulate the spontaneous decay of a two-state atom. in contrast, the validity of a deterministic algorithm based on the stochastic scheme is investigated. moreover, a mixed random-deterministic approach is established and its efficiency is exemplified by studying the exact dynamics for the spin-boson model at zero temperature.
