ON THE REAL MATRIX REPRESENTATION OF PT-SYMMETRIC OPERATORS

Francisco M. Fernández

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.
