Abstract

We design high order accurate methods that exploit low rank structure in the density matrix while respecting the essential structure of the Lindblad equation. Our methods preserves complete positivity and are trace preserving.

克劳斯为王：Lindblad主方程的高阶完全正迹保持（CPTP）低阶方法

我们设计了高阶精确的方法，利用密度矩阵中的低秩结构，同时尊重Lindblad方程的本质结构。我们的方法保留了完全的正性，并保留了痕迹。

期刊介绍： Journal of Computational Physics thoroughly treats the computational aspects of physical problems, presenting techniques for the numerical solution of mathematical equations arising in all areas of physics. The journal seeks to emphasize methods that cross disciplinary boundaries. The Journal of Computational Physics also publishes short notes of 4 pages or less (including figures, tables, and references but excluding title pages). Letters to the Editor commenting on articles already published in this Journal will also be considered. Neither notes nor letters should have an abstract.
