Duffin-Kemmer-Petiau formalism reexamined: non-relativistic approximation for spin 0 and spin 1 particles in a Riemannian space-time
It is shown that the generally covariant Duffin-Kemmer-Petiau equation, formulated in the frame of the Tetrode-Weyl-Fock-Ivanenko tetrad formalism, allows for a non-relativistic approximation if theExpand

Behavior of the spin of ultrarelativistic electrons in electrostatic fields with axial symmetry
The phenomenon of spin self-orientation of ultrarelativistic electrons in an external axially symmetric focusing electrostatic field is studied. The conditions for the existence of such collectiveExpand
Behavior of electron spin in an external axisymmetric electrostatic field
The self-orientation of the spin of an ultrarelativistic electron in an external axisymmetric focusing electrostatic field is investigated qualitatively. The conditions under which a collectiveExpand
Maxwell equations in complex form, squaring procedure and separating the variables
The Riemann–Silberstein–Majorana–Oppenheimer complex approach to the Maxwell electrodynamics is investigated within the matrix formalism. Within the squaring procedure we construct four types ofExpand
