自由变质量Klein-Gordon场的Wigner-Moyal描述

Wigner-Moyal description of free variable mass Klein-Gordon fields

J. P. Santos, L. O. Silva

摘要:

本文导出了自由变质量Klein-Gordon场维格纳分布的耦合动力学输运方程组。这组方程在形式上等价于非线性色散介质中电磁波的全波方程,从而允许描述宽带辐射-物质相互作用和相关的不稳定性。经典波作用量的标准结果在波动方程广义Wigner-Moyal形式的短波长极限下得到恢复。

英文摘要:

A system of coupled kinetic transport equations for the Wigner distributions of a free variable mass Klein-Gordon field is derived. This set of equations is formally equivalent to the full wave equation for electromagnetic waves in nonlinear dispersive media, thus allowing for the description of broadband radiation-matter interactions and the associated instabilities. The standard results for the classical wave action are recovered in the short wavelength limit of the generalized Wigner-Moyal formalism for the wave equation.
