Authors: Sh. M. Nagiyev, A. I. Ahmadov, and V. A. Tarverdiyeva
Abstract summary: We consider the quantum mechanical problem of the motion of a spinless charged relativistic particle with mass$M$. It is shown that the system under consideration has both a discrete at $left|Eright|Mc2 $ and a continuous at $left|Eright|>Mc2 $ energy spectra. It is also shown that relativistic expressions for wave functions, energy spectra and group generators in the limit $ctoinfty $ go over into the corresponding expressions for the nonrelativistic problem.

Abstract: We consider the quantum mechanical problem of the motion of a spinless charged relativistic particle with mass$M$, described by the Klein-Fock-Gordon equation with equal scalar $S(\vec{r})$ and vector $V(\vec{r})$ Coulomb plus ring-shaped potentials. It is shown that the system under consideration has both a discrete at $\left|E\right|<Mc^{2} $ and a continuous at $\left|E\right|>Mc^{2} $ energy spectra. We find the analytical expressions for the corresponding complete wave functions. A dynamical symmetry group $SU(1,1)$ for the radial wave equation of motion is constructed. The algebra of generators of this group makes it possible to find energy spectra in a purely algebraic way. It is also shown that relativistic expressions for wave functions, energy spectra and group generators in the limit $c\to \infty $ go over into the corresponding expressions for the nonrelativistic problem.

We apply an isosceles triangular-pulse function set for the Marchenko equation input kernel expansion in a separable form. We show that in the general case of a single partial wave, a linear expression of the input kernel is obtained. We show that energy-independent complex partial potentials describe these data for single $P$-waves.

Energy spectrum of massive Dirac particles in gapped graphene with Morse potential [0.0]
We study the massive Dirac equation with the presence of the Morse potential in polar coordinate. The Dirac Hamiltonian is written as two second-order differential equations in terms of two spinor wavefunctions. We investigate the graphene band structure by a linear dispersion relation which creates an energy gap in the Dirac points called gapped graphene.
