摘要翻译:
用4n×4n矩阵的对角化显式求解任意二次n个费米子系统的Lindblad主方程,条件是所有Lindblad浴算符在费米子变量中都是线性的。将该方法应用于横向磁场中最近邻Heisenberg XY自旋1/2链中热和自旋输运的远平衡问题的非平衡定态的显式构造和渐近弛豫速率的计算。

英文摘要:
The Lindblad master equation for an arbitrary quadratic system of n fermions is solved explicitly in terms of diagonalization of a 4n x 4n matrix, provided that all Lindblad bath operators are linear in the fermionic variables. The method is applied to the explicit construction of non-equilibrium steady states and the calculation of asymptotic relaxation rates in the far from equilibrium problem of heat and spin transport in a nearest neighbor Heisenberg XY spin 1/2 chain in a transverse magnetic field.
