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…
Spin and pseudospin symmetries of the Dirac equation with confining central potentials
P. Alberto, A. S. de Castro, M. Malheiro
We derive the node structure of the radial functions which are solutions of the Dirac equation with scalar and vector confining central potentials, in the conditions of exa…
Spin and pseudospin symmetries in the antinucleon spectrum of nuclei
R. Lisboa, M. Malheiro, P. Alberto +2
Spin and pseudospin symmetries in the spectra of nucleons and antinucleons are studied in a relativistic mean-field theory with scalar and vector Woods-Saxon potentials, in which t…
Spin and pseudospin symmetries and the equivalent spectra of relativistic spin-1/2 and spin-0 particles
P. Alberto, A. S. de Castro, M. Malheiro
We show that the conditions which originate the spin and pseudospin symmetries in the Dirac equation are the same that produce equivalent energy spectra of relativistic spin-1/2 an…
Relating pseudospin and spin symmetries through charge conjugation and chiral transformations: the case of the relativistic harmonic oscillator
A. S. de Castro, P. Alberto, R. Lisboa +1
We solve the generalized relativistic harmonic oscillator in 1+1 dimensions, i.e., including a linear pseudoscalar potential and quadratic scalar and vector potentials which have e…
Electrically charged compact stars
Subharthi Ray, Manuel Malheiro, Jose' P. S. Lemos +1
We review here the classical argument used to justify the electrical neutrality of stars and show that if the pressure and density of the matter and gravitational field inside the…
