Pure Coulomb tensor interaction in the Dirac equation

Autor: Garcia, M. G., Pratapsi, S., Alberto, P., de Castro, A. S.

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 depends on the sign the tensor constant potential, and allows only bou

Solutions of the three-dimensional radial Dirac equation from the Schr\'odinger equation with one-dimensional Morse potential

Autor: Garcia, M. G., de Castro, A. S., Alberto, P., Castro, L. B.

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 nonrelativistic bound-state solutions of the one-dimensional generali

Publikováno v: Annals of Physics 378 (2017) 88-99

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 nonrelativistic bound-state solutions of the one-dimensional generalized Mors

A complete set of eigenstates for position-dependent massive particles in a Morse-like scenario

Autor: Correa, R. A. C., Dutra, A. de Souza, de Oliveira, J. A., Garcia, M. G.

Publikováno v: Journal of Mathematical Physics 58, 012104 (2017)

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 the exact wavefunctions and energies for a complete set of eigenstates

Relativistic Coulomb scattering of spinless bosons

Autor: Garcia, M. G., de Castro, A. S.

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 the partial wave series reduces the scattering amplitude to the close

Report

Scattering and bound states of spinless particles in a mixed vector-scalar smooth step potential

Autor: Garcia, M. G., de Castro, A. S.

Publikováno v: Annals Phys.324:2372-2384,2009

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 mixing of vector and scalar Lorentz structures. The problem is mapped in
