Comment on "Dirac fermions in Som-Raychaudhuri space-time with scalar and vector potential and the energy momentum distributions"
Francisco A. Cruz Neto, Andrés G. Jirón Vicente, Luis B. Castro
We point out a misleading treatment and incorrect expressions in a recent paper published in this Journal [Eur. Phys. J. C (2019) 79: 541] regarding solutions for the Dirac equatio…
Scalar bosons with Coulomb potentials in a cosmic string background: Scattering and bound states
Francisco A. Cruz Neto, Franciele M. da Silva, Luis C. N. Santos +1
The relativistic quantum motion of scalar bosons under the influence of a full vector (minimal and nonminimal ) and scalar () interactions embedded in the backgro…
Proper treatment of scalar and vector exponential potentials in the Klein-Gordon equation: Scattering and bound states
Elvis J. Aquino Curi, Luis B. Castro, Antonio S. de Castro
We point out a misleading treatment in the literature regarding to bound-state solutions for the -wave Klein-Gordon equation with exponential scalar and vector potentials. Follo…
On the 2D Dirac oscillator in the presence of vector and scalar potentials in the cosmic string spacetime in the context of spin and pseudospin symmetries
Daniel F. Lima, Fabiano M. Andrade, Luis B. Castro +2
The Dirac equation with both scalar and vector couplings describing the dynamics of a two-dimensional Dirac oscillator in the cosmic string spacetime is considered. We derive the D…
Relativistic quantum dynamics of scalar bosons under a full vector Coulomb interaction
Luis B. Castro, Luiz P. de Oliveira, Marcelo G. Garcia +1
The relativistic quantum dynamics of scalar bosons in the background of a full vector coupling (minimal plus nonminimal vector couplings) is explored in the context of the Duffin-K…
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…
