物理学中尚未严格解决的基本问题之一是非平衡过程的统计力学。从可逆哈密顿动力学出发，D. N. Zubarev，他发明了非平衡统计算子的方法。我们讨论这种方法，特别是，扩展冯诺依曼方程，并作为一个例子考虑带电粒子系统的电导率。我们考虑相关观测量集合的选择。我们显示动力学理论和线性响应理论之间的关系。利用热力学绿色函数，我们提出了一个系统的处理相关函数，但收敛性需要调查。我们比较了不同的表达式的电导率和列表开放的问题。
One of the fundamental problems in physics that are not yet rigorously solved is the statistical mechanics of nonequilibrium processes. An important contribution to describing irreversible behavior starting from reversible Hamiltonian dynamics was given by D. N. Zubarev, who invented the method of the nonequilibrium statistical operator. We discuss this approach, in particular, the extended von Neumann equation, and as an example consider the electrical conductivity of a system of charged particles. We consider the selection of the set of relevant observables. We show the relation between kinetic theory and linear response theory. Using thermodynamic Green’s functions, we present a systematic treatment of correlation functions, but the convergence needs investigation. We compare different expressions for the conductivity and list open questions.
