Pseudo Hermitian interactions in the Dirac equation

Abstract

We consider a (2 + 1)-dimensional massless Dirac equation in the presence of complex vector potentials. It is shown that such vector potentials (leading to complex magnetic fields) can produce bound states, and the Dirac Hamiltonians are n{right tail}-pseudo Hermitian. Some examples have been explicitly worked out © 2014 by the authors; licensee MDPI, Basel, Switzerland.
