We study the St¨ uckelberg equation for a relativistic particle with two spin states S= 1 and
S= 0 in the presence of an external uniform magnetic field. The particle is described by an …

The system of 10 radial equations, derived from the Duffin–Kemmer–Petiau equation for a
spin 1 particle in the external Coulomb field, is studied. With the use of the space reflection …

We examine the basic matrix equation for a spin-2 field in spherical coordinates and a tetrad
of Minkowski spacetime. The technique of Wigner D-functions is used to separate the …

The known result that electromagnetic solutions in the form of the gradient of an arbitrary
scalar function make a zero contribution to the energy-momentum tensor is extended to a …

In the context of the composite boson interpretation, we construct the exact general solution
of the Dirac–Kähler equation for the case of the spherical Riemann space of constant …

In the paper, the well-known quantum mechanical problem of a spin 1/2 particle in external
Coulomb potential, reduced to a system of two first-order differential equations, is studied …

Influence of the geometry on the particles with spin 1/2 (nonrelativistic electron or neutron
described by a generalized Pauli equation on the background of the non-Euclidean …

Tetrad-based generalized complex formalism by Majorana--Oppenheimer is applied to treat
electromagnetic field in extending de Sitter Universe in on-static spherically-symmetric …
