晶体光学中的圆双折射

Circular birefringence in crystal optics

Richard J. Potton

摘要:

在晶体光学中,晶体静止坐标系的特殊地位意味着时空对称性对电动力学现象的限制比静态电磁效应的限制要小。一个相对论的理由,这种说法提供和其后果的分析旋光活性进行了探讨。离散的时空对称性P和T,导致分类的静态属性张量作为极性或轴向,时不变(-i)或时变(-c)被连接的方向考虑。这种联系在某些对称性决定的晶体类中表现为回转性的动力学现象。特别地,光学活性晶体中的前向波和后向波的简并性来自于时空(PT)反转下的波动方程的协方差。

英文摘要:

In crystal optics the special status of the rest frame of the crystal means that space-time symmetry is less restrictive of electrodynamic phenomena than it is of static electromagnetic effects. A relativistic justification for this claim is provided and its consequences for the analysis of optical activity are explored. The discrete space-time symmetries P and T that lead to classification of static property tensors as polar or axial, time-invariant (-i) or time-change (-c) are shown to be connected by orientation considerations. The connection finds expression in the dynamic phenomenon of gyrotropy in certain, symmetry determined, crystal classes. In particular, the degeneracies of forward and backward waves in optically active crystals arise from the covariance of the wave equation under space-time (PT) reversal.
