On the real matrix representation of PT-symmetric operators

Quantum Physics 2014-04-16 v4

Abstract

We discuss the construction of real matrix representations of PT-symmetric operators. We show the limitation of a general recipe presented some time ago for non-Hermitian Hamiltonians with antiunitary symmetry and propose a way to overcome it. Our results agree with earlier ones for a particular case.
