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 η-pseudo Hermitian. Some examples have been explicitly worked out.
Keywords: pseudo Herimitian Hamiltonians; two-dimensional Dirac Equation; complex magnetic fields. pseudo Herimitian Hamiltonians; two-dimensional Dirac Equation; complex magnetic fields.
