PT-symmetric quantum mechanics is a Hermitian quantum mechanics

Sungwook Lee

The author introduces a different kind of Hermtian quantum mechanics, called J-Hermitian quantum mechanics. He shows that PT-symmetric quantum mechanics is indeed J-Hermitian quantum mechanics, and that temporal evolution is unitary if and only if Hamiltonian is PT-symmetric.
