Non-Hermitian PT-symmetric and Hermitian Hamiltonians' correspondence: Isospectrality and mass signature

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/170834A transformation of the form x to iy; x,y in R, or an equivalent similarity transformation with a metric operator $η$ are shown to transform non-Hermitian PT-symmetric Hamiltonians into Hermitian partner Hamiltonians in Hilbert space. Isospectrality and mass signature are discussed.16 pages, no figuresQuantum PhysicsNon-Hermitian PT-symmetric and Hermitian Hamiltonians' correspondence: Isospectrality and mass signaturetext
