论文摘要
我们扩展了一种先前开发的方法，以在高温方向和幅度的经典范围内关联热电流。我们考虑双聚体标量理论，该理论具有立方体理论的基本结构，并且通过双拷贝与QCD和重力有关。此外，我们考虑了标量QED对模型的经典自旋的概括，其中大量标量是复杂的高旋转场。我们为双聚体标量推导了Vlasov型动力学方程并研究其迭代溶液，而对于QED，我们使用了众所周知的动力学方程。在这两种情况下，我们都会发现这些解决方案与振幅样方法之间的一致性。
We extend a previously developed approach to relate thermal currents in the high temperature regime and classical limits of amplitudes. We consider the bi-adjoint scalar theory, which has the basic structure of a cubic theory and which is related to QCD and gravity through the double copy. In addition, we consider a generalization of scalar QED to model classical spin, where massive scalars are complex higher-spin fields. We derive Vlasov-type kinetic equations for bi-adjoint scalars and study their iterative solutions, while for QED we use well-known kinetic equations. In both cases we find consistency between these solutions and the amplitude-like approach.
