PT-Symmetry Quantum Electrodynamics--PTQED

Abstract

The construction of $\mathcal{P}\mathcal{T}$-symmetric quantum electrodynamics is reviewed. In particular, the massless version of the theory in 1+1 dimensions (the Schwinger model) is solved. Difficulties with unitarity of the $S$-matrix are discussed.
