Title: | Higher-order solutions to non-Markovian quantum dynamics via a hierarchical functional derivative | Authors: | Luo, DW Lam, CH Wu, LA Yu, T Lin, HQ You, JQ |
Issue Date: | Aug-2015 | Source: | Physical review. A, Atomic, molecular, and optical physics, Aug. 2015, v. 92, no. 2, 022119 | Abstract: | Solving realistic quantum systems coupled to an environment is a challenging task. Here we develop a hierarchical functional derivative (HFD) approach for efficiently solving the non-Markovian quantum trajectories of an open quantum system embedded in a bosonic bath. An explicit expression for arbitrary order HFD equation is derived systematically. Moreover, it is found that for an analytically solvable model, this hierarchical equation naturally terminates at a given order and thus becomes exactly solvable. This HFD approach provides a systematic method to study the non-Markovian quantum dynamics of an open system coupled to a bosonic environment. | Publisher: | American Physical Society | Journal: | Physical review.
