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…
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…
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…
Spinless bosons embedded in a vector Duffin-Kemmer-Petiau oscillator
L. B. Castro, A. S. de Castro
Some properties of minimal and nonminimal vector interactions in the Duffin-Kemmer-Petiau (DKP) formalism are discussed. The conservation of the total angular momentum for spherica…
Effects due to a scalar coupling on the particle-antiparticle production in the Duffin-Kemmer-Petiau theory
T. R. Cardoso, L. B. Castro, A. S. de Castro
The Duffin-Kemmer-Petiau formalism with vector and scalar potentials is used to point out a few misconceptions diffused in the literature. It is explicitly shown that the scalar co…
