Real spectra for the non-Hermitian Dirac equation in 1+11+1 dimensions with the most general coupling

The most general combination of couplings of fermions with external potentials in 1+11+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 Schrödinger equation. Despite the non-hermiticity of the effective potential, we find real energies for the fermion.
