  • Title: Exact quantum master equation via the calculus on path integrals.
    Author: Xu RX, Cui P, Li XQ, Mo Y, Yan Y.
    Journal: J Chem Phys; 2005 Jan 22; 122(4):41103. PubMed ID: 15740228.
    Abstract:
    An exact quantum master equation formalism is constructed for the efficient evaluation of quantum non-Markovian dissipation beyond the weak system-bath interaction regime in the presence of time-dependent external field. A novel truncation scheme is further proposed and compared with other approaches to close the resulting hierarchically coupled equations of motion. The interplay between system-bath interaction strength, non-Markovian property, and required level of hierarchy is also demonstrated with the aid of simple spin-boson systems.
