Title: | Approach to solving spin-boson dynamics via non-Markovian quantum trajectories | Authors: | Li, ZZ Yip, CT Deng, HY Chen, M Yu, T You, JQ Lam, CH |
Issue Date: | Aug-2014 | Source: | Physical review. A, Atomic, molecular, and optical physics, Aug. 2014, v. 90, no. 2, 22122 | Abstract: | We develop a systematic and efficient approach for numerically solving the non-Markovian quantum state diffusion equation for an open quantum system that can be strongly coupled to an environment. As an important application, we consider a real-time simulation of a spin-boson model in a strong-coupling regime that is difficult to deal with using conventional methods. We show that the non-Markovian stochastic Schrodinger equation can be efficiently implemented as a real-time simulation for this model, so as to give an accurate description of spin-boson dynamics beyond the rotating-wave approximation. | Publisher: | American Physical Society | Journal: | Physical review.
