Anomalous Faraday effect in a PT-symmetric dielectric slab
Abstract
In this letter we discuss a phase transition-like anomalous behavior of Faraday rotation angles in a simple parity-time (PT) 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 turns negative, and both angles suffer spectral singularities and yield strong enhancement near singularities.
