Abstract:
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 Schr¨odinger equation. Despite the non-hermiticity
of the effective potential, we find real energies for the fermion.
