Extension of PT-symmetric quantum mechanics to the Dirac theory with position-dependent mass
(Academic Press Inc. Elsevier B.V., 2008-03-01)
We present a new method to construct the exactly solvable PT-symmetric potentials within the framework of the position-dependent effective mass Dirac equation with the vector potential coupling scheme in 1 + 1 dimensions. ...

(Iop Publishing Ltd, 2006-09-22)
We present a new procedure to construct the one-dimensional non-Hermitian imaginary potential with a real energy spectrum in the context of the position-dependent effective mass Dirac equation with the vector-coupling ...

On the Dirac equation with PT-symmetric potentials in the presence of position-dependent mass
(Elsevier B.V., 2011-06-20)
The relativistic problem of fermions subject to a PT-symmetric potential in the presence of position-dependent mass is reinvestigated. The influence of the FT-symmetric potential in the continuity equation and in the ...

Comment on "Numerical estimates of the spectrum for anharmonic PT symmetric potentials"
(IOP Publishing, 2013-03)
We show that the authors of the commented paper (Bowen et al 2012 Phys. Scr. 85 065005) draw their conclusions from the eigenvalues of truncated Hamiltonian matrices that do not converge as the matrix dimension increases. ...
