Pseudospin symmetry and the relativistic harmonic oscillator
R. Lisboa, M. Malheiro, A. S. de Castro +2
A generalized relativistic harmonic oscillator for spin 1/2 particles is studied. The Dirac Hamiltonian contains a scalar and a vector quadratic potentials in the radial co…
Electrically charged compact stars and formation of charged black holes
Subharthi Ray, Aquino L. Espindola, Manuel Malheiro +2
We study the effect of electric charge in compact stars assuming that the charge distribution is proportional to the mass density. The pressure and the density of the matter inside…
Role of the Coulomb and the vector-isovector potentials in the isospin asymmetry of nuclear pseudospin
R. Lisboa, M. Malheiro, P. Alberto
We investigate the role of the Coulomb and the vector-isovector potentials in the asymmetry of the neutron and proton pseudospin splittings in nuclei. To this end, we solve the…
