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 …

We present the first experimental microwave realization of the one-dimensional Dirac
oscillator, a paradigm in exactly solvable relativistic systems. The experiment relies on a …

We introduce a unique model for a fermion-antifermion pair interacting via Dirac oscillator
coupling in the presence of an external uniform magnetic field. This model is based on an …

Relativistic symmetries of the Dirac equation, namely the spin and pseudospin symmetries,
are investigated under the Tietz potential for the scalar and vector interactions beside a …

Using the basic concept of the supersymmetric shape invariance approach and formalism,
we obtained an approximate solution of the Schrödinger equation with an interaction of …

Based on the significant role of spin and pseudospin symmetries in hadron and nuclear
spectroscopy, we have investigated Dirac equation under scalar and vector potentials of …

Approximate analytical solutions of the D-dimensional Klein—Gordon equation are obtained
for the scalar and vector general Hulthén-type potential and position-dependent mass with …

Applying an appropriate approximation scheme to deal with the centrifugal term, pseudospin
and spin symmetric solutions of the Dirac–Yukawa problem with tensor interaction are …

Approximate analytical solutions of a Duffin-Kemmer-Petiau (DKP) equation are obtained
via an elegant ansatz after successive transformations. Apart from the wide application of the …

The origin of pseudospin symmetry (PSS) and its breaking mechanism are explored by
combining supersymmetry (SUSY) quantum mechanics, perturbation theory, and the …
