Pure Coulomb tensor interaction in the Dirac equation
M. G. Garcia, S. Pratapsi, P. Alberto +1
In this work we compute bound solutions for particles and anti-particles of the Dirac equation for a pure tensor radial Coulomb potential plus a constant. We find that the binding…
Solutions of the three-dimensional radial Dirac equation from the Schrödinger equation with one-dimensional Morse potential
M. G. Garcia, A. S. de Castro, P. Alberto +1
New exact analytical bound-state solutions of the radial Dirac equation in 3+1 dimensions for two sets of couplings and radial potential functions are obtained via mapping onto the…
New solutions of the D-dimensional Klein-Gordon equation via mapping onto the nonrelativistic one-dimensional Morse potential
M. G. Garcia, A. S. de Castro, L. B. Castro +1
New exact analytical bound-state solutions of the D-dimensional Klein-Gordon equation for a large set of couplings and potential functions are obtained via mapping onto the nonrela…
A complete set of eigenstates for position-dependent massive particles in a Morse-like scenario
R. A. C. Correa, A. de Souza Dutra, J. A. de Oliveira +1
In this work we analyze a system consisting in two-dimensional position-dependent massive particles in the presence of a Morse-like potential in two spatial dimensions. We obtain t…
Relativistic Coulomb scattering of spinless bosons
M. G. Garcia, A. S. de Castro
The relativistic scattering of spin-0 bosons by spherically symmetric Coulomb fields is analyzed in detail with an arbitrary mixing of vector and scalar couplings. It is shown that…
Scattering and bound states of spinless particles in a mixed vector-scalar smooth step potential
M. G. Garcia, A. S. de Castro
Scattering and bound states for a spinless particle in the background of a kink-like smooth step potential, added with a scalar uniform background, are considered with a general mi…
