B. Real spectra for the non-Hermitian Dirac equation in $1+1$ dimensions with the
most general coupling. |
| 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. |
