Real spectra for the non-Hermitian Dirac equation in 1+1 dimensions with the most general coupling
(Elsevier B.V., 2009-09-14)
The most general combination of couplings of fermions with external potentials in 1 + 1 dimensions, must include vector, scalar and pseudoscalar potentials. We consider such a mixing of potentials in a PT-symmetric ...

Non-Hermitian oscillators with Td symmetry
(Academic Press Inc Elsevier Science, 2015-02)
We analyse some PT-symmetric oscillators with Td symmetry that depend on a potential parameter g. We calculate the eigenvalues and eigenfunctions for each irreducible representation and for a range of values of g. Pairs ...
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 ...

Time-dependent non-Hermitian Hamiltonians with real energies
(Edp Sciences S A, 2005-07-01)
In this work we intend to study a class of time-dependent quantum systems with non-Hermitian Hamiltonians, particularly those whose Hermitian counterparts are important for the comprehension of posed problems in quantum ...
