A description of dislocation and disclination defects in terms of the Riemann–Cartan
geometry is given, with the curvature and torsion tensors interpreted as the surface densities …

The behaviour of the Klein-Gordon oscillator under the influence of linear and Coulomb-type
potentials is investigated. The introduction of the scalar potentials is made by modifying the …

The relativistic quantum dynamics of an electrically charged particle subject to the Klein–
Gordon oscillator and the Coulomb potential is investigated. By searching for relativistic …

We consider a spherical quantum dot described by an attractive short-range potential and
search for topological effects of a global monopole on it. The attractive short-range potential …

We analyse the influence of spiral dislocation topology on the revival time for the harmonic
oscillator, for a particle confined to one-dimensional quantum ring, and a two-dimensional …

In this paper, we investigate the influence of the background of a cosmic string space–time
with a distortion of a radial line into a spiral on the interaction of the scalar field with a …

We revisit the interaction between a point charge and an inhomogeneous magnetic field that
yields the magnetic quantum dot system. This magnetic field is defined by filling the whole …

We investigate the arising of an analogue of the Landau quantization from a background of
the violation of the Lorentz symmetry established by a time-like four-vector and a field …

We study the effects of the spiral dislocation topology on the confinement of a point charge
(electron or hole) to a cylindrical wire in a rotating reference frame. In addition, we consider …

Based on the power-exponential potential model for quantum dots, we study the
confinement of a particle to a spherical quantum dot from a long-range potential. We show …
