论文摘要
在这封信中，我们讨论了在简单的平等时段（$ \ \ \ \ \ m rathcal {p} \ mathcal {t} $）对称模型的相变旋转角的类似相变的异常行为，其中两个复杂的$Δ$ - 电位放置在常规介电板的两个边界上。在异常阶段，法拉第旋转角度的值可能会变为负，并且两个角度都具有频谱奇点，并在奇异点附近产生强大的增强。
In this letter we discuss a phase transition-like anomalous behavior of Faraday rotation angles in a simple parity-time ($\mathcal{P}\mathcal{T}$) symmetric model with two complex $δ$-potential placed at both boundaries of a regular dielectric slab. In anomalous phase, the value of one of Faraday rotation angles may turn negative, and both angles suffer spectral singularities and yield strong enhancement near singularities.
