关于Maxwell场的直接量子化

On the direct quantization of Maxwell field

Warda Benarab, Zahir Belhadi

AI总结:

本文应用广义积分常数方法对Maxwell和Klein-Gordon自由场进行直接量子化,通过Taylor展开和Helmholtz分解处理约束,获得场及其共轭动量的等时Dirac括号。

摘要:

本文将场论中的广义积分常数方法应用于Maxwell和Klein-Gordon自由场的量子化。研究在位置空间和动量空间中进行,以获得场及其共轭动量之间的等时Dirac括号。其思路是利用Taylor多项式展开在初始时刻附近获得这些括号,随后直接推导出它们在任意后续时刻的表达式。对于Maxwell场,场分量之间的相互依赖性(约束)要求使用Helmholtz定理来分离横向和纵向部分。关键词:奇异系统、约束、Dirac括号、CI方法、Taylor展开、KG场、Maxwell场、Fourier变换、Helmholtz分解。

英文摘要:

In this paper, we apply the generalized integration constants method in field theory to quantize Maxwell and the Klein-Gordon free fields. The study is performed in both position and momentum spaces, to obtain equal-time Dirac brackets among the fields and their conjugate momenta. The idea is to obtain the brackets near the initial instant using the Taylor polynomial expansion, and then deduce directly their expressions at any later time. In the case of the Maxwell field, the interdependence of the field components (constraints) requires the use the Helmholtz theorem to separate the transversal and longitudinal parts. Keywords : Singular systems, constraints, Dirac brackets, CI method, Taylor expansion, KG field, Maxwell field, Fourier transform, Helmholtz decomposition.
