Eigenvalue Spectrum of a Dirac Particle in Static and Spherical Complex Potential
It has been observed that a quantum theory need not to be Hermitian to have a
real spectrum. We study the non-Hermitian relativistic quantum theories for
many complex potentials, and we obtain the real relativistic energy eigenvalues
and corresponding eigenfunctions of a Dirac charged particle in complex static
and spherically symmetric potentials. Complex Dirac-Eckart, complex
Dirac-Rosen-Morse II, complex Dirac-Scarf and complex Dirac-Poschl-Teller
potential are investigated.Comment: 9 pages, no fiugres, late
Spin Zero Quantum Relativistic Particles in Einstein Universe
In this letter we have considered the eigenvalues and eigenfunctions of
relativistic massless scalar particle which conformally coupled to the
background of Einstein universe. We found the eigenvalues and eigenfunctions
exactly.Comment: 4 pages, no figure, accepted for publication in International Journal
