Abstract

Exceptional points in parity-time symmetric optics and photonics have in recent years been promoted in various contexts of light-matter interactions. In particular, the spectrum with coalescing eigenvalues changes dramatically the photonics system's response to perturbations. The talk will discuss both some fundamental aspects of this, including limitations associated with causality, as well as some of the pros and cons for pratical sensor applications, including the noise limitations on the detection limit.
