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…
Unsuitable use of spin and pseudospin symmetries with a pseudoscalar Cornell potential
L. B. Castro, A. S. de Castro
The concepts of spin and pseudospin symmetries has been used as mere rhetorics to decorate the pseudoscalar potential [Chin. Phys. B 22 090301 (2013)]. It is also pointed out that…
Corroborating the equivalence between the Duffin-Kemmer-Petiau and the Klein-Gordon and Proca equations
L. B. Castro, A. S. de Castro
It is shown that the Hamiltonian version of the Duffin-Kemmer-Petiau theory with electromagnetic coupling brings about a source term at the current. It is also shown that such a so…
Missing solution in a Cornell potential
L. B. Castro, A. S. de Castro
Missing bound-state solutions for fermions in the background of a Cornell potential consisting of a mixed scalar-vector-pseudoscalar coupling is examined. Charge-conjugation operat…
Relating pseudospin and spin symmetries through chiral transformation with tensor interaction
L. B. Castro
We address the behavior of the Dirac equation with scalar (), vector () and tensor () interactions under the discrete chiral transformation. Using this transformat…
An effective singular oscillator for Duffin-Kemmer-Petiau particles with a nonminimal vector coupling: a two-fold degeneracy
T. R. Cardoso, L. B. Castro, A. S. de Castro
Scalar and vector bosons in the background of one-dimensional nonminimal vector linear plus inversely linear potentials are explored in a unified way in the context of the Duffin-K…
