光子在非平凡背景中的传输

Photon propagation in non-trivial backgrounds

Palash B. Pal

摘要:

光子(或任何自旋为1的玻色子)在不同类型的非平凡背景中的传播是令人感兴趣的,包括热浴或背景磁场,或两者兼而有之。我们给一个统一的治疗所有这样的情况下,铸造的问题作为一个矩阵特征值问题。所讨论的矩阵不是正规矩阵,因此应注意区分右特征向量和左特征向量。证明了极化向量是该矩阵的右特征向量,极化和公式是特征向量的完备关系。我们展示了这种方法是如何成功地应用到不同的非平凡的背景。

英文摘要:

Propagation of photons (or of any spin-1 boson) is of interest in different kinds of non-trivial background, including a thermal bath, or a background magnetic field, or both. We give a unified treatment of all such cases, casting the problem as a matrix eigenvalue problem. The matrix in question is not a normal matrix, and therefore care should be given to distinguish the right eigenvectors from the left eigenvectors. The polarization vectors are shown to be right eigenvectors of this matrix, and the polarization sum formula is seen as the completeness relation of the eigenvectors. We show how this method is successfully applied to different non-trivial backgrounds.
