论文摘要
在本文中，我们应用嵌套的代数贝尔·安萨兹（Bethe ansatz）来计算[1]中发现的新的可集成lindbladian的转移矩阵的特征值和伯特方程。我们证明它可以写成一个可集成的自旋链，该链条由两个相互作用的XXZ旋转链组成。我们从数值上计算Liouville差距及其对系统中参数的依赖性，例如按系统的长度和相互作用强度进行缩放。
In this paper we apply the nested algebraic Bethe ansatz to compute the eigenvalues and the Bethe equations of the transfer matrix of the new integrable Lindbladian found in [1]. We show that it can be written as an integrable spin chain consisting of two interacting XXZ spin chains. We numerically compute the Liouville gap and its dependence on the parameters in the system such as scaling with the system length and interaction strength.
