张量网络我们进一步认为，NESS可以通过动态演化系统中适当的低纠缠态的流形。一个物理上现实的动力学演化定律是马尔可夫开放系统动力学，或林德布拉德方程。我们探索这种方法在一个研究充分的自由费米子模型与文献的比较是可能的。我们研究了有无无序的电流和热流，并计算了互信息和条件互信息等熵量。最后，我们讨论了这种方法的前景具有挑战性的问题，在强相互作用的系统，特别是那些无序的运输。
tensor network. We further argue that the NESS may be found by dynamically evolving the system within a manifold of appropriate low entanglement states. A physically realistic law of dynamical evolution is Markovian open system dynamics, or the Lindblad equation. We explore this approach in a well-studied free fermion model where comparisons with the literature are possible. We study both electrical and thermal currents with and without disorder, and compute entropic quantities such as mutual information and conditional mutual information. We conclude with a discussion of the prospects of this approach for the challenging problem of transport in strongly interacting systems, especially those with disorder.
