论文摘要
一个长期以来表征开放马尔可夫量子系统演变的工具是GKSL（Gorini-Kossakowski-Sudarshan-Lindblad）主方程。但是，在某些情况下，可以用非富尔顿顿人有效地描述开放量子系统，由于许多非常规的特性，例如出现特殊点，这在过去二十年中引起了极大的兴趣。在这里，我们对这两种不同的方法进行了简短的评论，尤其是旨在突出它们的关系，并说明将非热汉密尔顿的不同方法与GKSL主方程连接到全密度矩阵。
A longstanding tool to characterize the evolution of open Markovian quantum systems is the GKSL (Gorini-Kossakowski-Sudarshan-Lindblad) master equation. However, in some cases, open quantum systems can be effectively described with non-Hermitian Hamiltonians, which have attracted great interest in the last twenty years due to a number of unconventional properties, such as the appearance of exceptional points. Here, we present a short review of these two different approaches aiming in particular to highlight their relation and illustrate different ways of connecting non-Hermitian Hamiltonian to a GKSL master equation for the full density matrix.
