(1+1) dimensional Dirac equation with non Hermitian interaction
A. Sinha, P. Roy
Abstract
We study (1+1) dimensional Dirac equation with non Hermitian interactions, but real energies. In particular, we analyze the pseudoscalar and scalar interactions in detail, illustrating our observations with some examples. We also show that the relevant hidden symmetry of the Dirac equation with such an interaction is pseudo supersymmetry.
