我们提出了一个共形场论内的非平衡定态的建设。这些状态维持两个量子系统之间的能量流动，最初在不同的温度下制备，其动力学性质由两个可能不同的共形场论通过杂质连接表示。这种结构依赖于一个真实的时间公式的共形缺陷动力学的基础上的场散射图片平行化，但又不同的欧几里德公式。我们提出的基本特点，这一提法，并给出了代数结构的真实的时间散射地图，我们说明的情况下，SU（2）？>基于共形场论
We present a construction of non-equilibrium steady states within conformal field theory. These states sustain energy flows between two quantum systems, initially prepared at different temperatures, whose dynamical properties are represented by two, possibly different, conformal field theories connected through an impurity. This construction relies on a real time formulation of conformal defect dynamics based on a field scattering picture parallelizing—but yet different from—the Euclidean formulation. We present the basic characteristics of this formulation and give an algebraic construction of the real time scattering maps that we illustrate in the case of SU ( 2 ) ?> -based conformal field theories.
