TLDR
In this paper, the Lindblad master equation for an arbitrary quadratic system of n fermions is solved explicitly in terms of diagonalization of a 4n?4n matrix, provided that all bath operators are linear in the fermionic variables.
Abstract
The Lindblad master equation for an arbitrary quadratic system of n fermions is solved explicitly in terms of diagonalization of a 4n?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 (NESS) and the calculation of asymptotic relaxation rates in the far from equilibrium problem of heat and spin transport in a nearest neighbour Heisenberg XY spin-1/2 chain in a transverse magnetic field.

Quantum trajectories and open many-body quantum systems

TL;DR: Open quantum systems as discussed by the authors describe quantum systems exhibiting quantum coherence that are coupled to their environment, where the coupling to the environment is sufficiently well understood that it can be manipulated to drive the system into desired quantum states, or project the system onto known states via feedback in quantum measurements.
