Resumen
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 time-independent Dirac equation. The Dirac equation is mapped into an effective PT-symmetric Schrodinger equation. Despite the non-hermiticity of the effective potential, we find real energies for the fermion. (C) 2009 Elsevier B.V. All rights reserved.
