耦合变换下耗散电磁系统微观Lagrange量的导出

Derivation on microscopic Lagrangian of electromagnetic dispersion system under the coupling transform

以正常态的电子及简正模的振子集合为环境,分析了电磁系统与环境之间的耗散关系,计算了由此产生的相互作用Lagrange量,并通过坐标耦合变换,进一步导出了便于路径积分的总体系的微观Lagrange量的直观表示。

Considering normal electrons and normal mode oscillator aggregations as the surroundings, the paper has analyzed the dispersion relation between electromagnetic system and the surroundings,and has calculated the corresponding interacting Lagrangian.By using coordinate coupling transform,it has de-rived Lagrangian's visual denotation of total system,which is convenient for path integral.
