(1+1)-Dirac particle with position-dependent mass in complexified Lorentz scalar interactions: Effectively PT-symmetric

Mustafa, Omar; Mazharimousavi, Seyed Habib (SPRINGER/PLENUM PUBLISHERS, 2008-04)

The effect of the built-in supersymmetric quantum mechanical language on the spectrum of the (1 + 1)-Dirac equation, with position-dependent mass (PDM) and complexified Lorentz scalar interactions, is re-emphasized. The ...
Complexified von Roos Hamiltonian's η-weak-pseudo-Hermiticity, isospectrality and exact solvability

Mustafa, Omar; Mazharimousavi, Seyed Habib (IOP Science, 2008-06)

A complexified von Roos Hamiltonian is considered and a Hermitian firstorder intertwining differential operator is used to obtain the related positiondependent mass η-weak-pseudo-HermitianHamiltonians. Using a Liouvilleantype ...
d-dimensional generalization of the point canonical transformation for a quantum particle with position-dependent mass

Mustafa, Omar; Mazharimousavi, Seyed Habib (IOP Science, 2006-08-02)

The d-dimensional generalization of the point canonical transformation for a quantum particle endowed with a position-dependent mass in the Schr¨odinger equation is described. Illustrative examples including the harmonic ...
