Title: Unmasking PT symmetry

Abstract: The theory of complex variables is extremely useful because it
helps to explain the mathematical behavior of functions of a real variable.
Complex variable theory also provides insight into the nature of physical
theories. For example, it provides a simple and beautiful picture of
quantization and it explains the underlying reason for the divergence of
perturbation theory. Complex-variable methods allow one to extend conventional Hermitian quantum theories into the complex domain. The result is a new class of parity-time-symmetric (PT-symmetric) theories whose remarkable physical properties have been studied and verified in many recent laboratory experiments.
