论文摘要
我们将流程方程的理论推广到打开关注Lindblad主方程的量子系统。我们介绍并讨论了流动的三个不同的发电机,这些发电机将线性非热运算符转化为对角线。我们首先在通用矩阵上测试耗散流动方程,并在具有驱动性的单一费用模式的物理问题上测试耗散方程。然后,我们通过许多费米子模式解决问题,并讨论相干(无序)动力学和局部损失之间的相互作用。我们的方法也可以应用于非热汉顿人。
We generalize the theory of flow equations to open quantum systems focusing on Lindblad master equations. We introduce and discuss three different generators of the flow that transform a linear non-Hermitian operator into a diagonal one. We first test our dissipative flow equations on a generic matrix and on a physical problem with a driven-dissipative single fermionic mode. We then move to problems with many fermionic modes and discuss the interplay between coherent (disordered) dynamics and localized losses. Our method can also be applied to non-Hermitian Hamiltonians.
