运动磁介电介质中电磁场量子化的正则相对论方法

A Canonical Relativistic Approach to Quantize Electromagnetic Field in the Presence of Moving Magneto-Dielectric Media

M. Amooshahi

摘要:

本文引入正则相对论公式,研究了可极化可磁化运动介质中的电磁场。介质是由一个连续的四个矢量在唯象的方式建模。利用整个系统的拉格朗日量,得到了矢量势的协变波动方程和协变介质本构方程的欧拉-拉格朗日方程。引入了一个耦合电磁场与介质的三阶张量,并由耦合张量得到了介质的磁化率张量。利用耦合张量和模拟介质的四个矢量的产生和湮灭算符计算了噪声极化张量。

英文摘要:

A canonical relativistic formulation is introduced to quantize electromagnetic field in the presence of a polarizable and magnetizable moving medium. The medium is modeled by a continuum of four vectors in a phenomenological way. The covariant wave equation for the vector potential and the covariant constitutive equation of the medium are obtained as the Euler- Lagrange equations using the Lagrangian of the total system. A tensor of the third rank which couples the electromagnetic field with the medium is introduced and the susceptibility tensor of the medium is obtained in terms of the coupling tensor. Also the noise polarization tensor is calculated in terms of the coupling tensor and the creation and annihilation operators of the four vectors modeling the medium.
