Symmetry plays a fundamental role in physics. The quasi-degeneracy between single- particle orbitals (n, l, j= l+ 1/2) and (n− 1, l+ 2, j= l+ 3/2) indicates a hidden symmetry in …
Relativistic symmetries of the Dirac Hamiltonian had been discovered many years ago but only recently have these symmetries been recognized empirically in nuclear and hadronic …

We perform a systematic study of the ground-state properties of all the nuclei from the proton drip line to the neutron drip line throughout the periodic table employing the relativistic mean …
Based on the Sturm–Liouville theorem and shape invariance formalism, we study by applying a Pekeris-type approximation to the pseudo-centrifugal term the pseudospin …
The pseudospin symmetry (PSS) is a relativistic dynamical symmetry connected with the small component of the Dirac spinor. The origin of PSS in single particle bound states in …

Pseudospin symmetry (PSS) is a relativistic dynamical symmetry connected with the lower component of the Dirac spinor. Here, we investigate the conservation and breaking of PSS …

Spin and pseudospin symmetries play vital roles in nuclear physics and have been studied extensively in spherical nuclei. However, there are much fewer studies in deformed systems …
In this study, the approximate analytical solutions of Schrödinger, Klein–Gordon and Dirac equations under the Tietz–Wei (TW) diatomic molecular potential are represented by using …
