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…
Relativistic particle in a box: Klein-Gordon vs Dirac Equations
Pedro Alberto, Saurya Das, Elias C. Vagenas
The problem of a particle in a box is probably the simplest problem in quantum mechanics which allows for significant insight into the nature of quantum systems and thus is a corne…
Temperature effects on nuclear pseudospin symmetry in the Dirac-Hartree-Bogoliubov formalism
R. Lisboa, P. Alberto, B. V. Carlson +1
We present finite temperature Dirac-Hartree-Bogoliubov (FTDHB) calculations for the tin isotope chain to study the dependence of pseudospin on the nuclear temperature. In the FTDHB…
Generalizing spin and pseudospin symmetries for relativistic spin 1/2 fermions
P. Alberto, M. Malheiro, T. Frederico +1
We propose a generalization of pseudospin and spin symmetries, the SU(2) symmetries of Dirac equation with scalar and vector mean-field potentials originally found independently in…
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…
