Pr\'ufer transformation and its application to the numerical description of the motion of quantum particles with various spins in the fields of classical black holes
Autor: V. P. Neznamov, I. I. Safronov, V. E. Shemarulin
Stable and reliable numerical integration of second-order radial equations in the fields of classical black holes can be performed by using the Pr\"ufer transformation and by passing to the use of phase functions, which allows uniquely selecting the

Quantum electrodynamics with self-conjugated equations with spinor wave functions for fermion fields
Autor: V. P. Neznamov, V. E. Shemarulin
Quantum electrodynamics (QED) with self-conjugated equations with spinor wave functions for fermion fields is considered. In the low order of the perturbation theory, matrix elements of some of QED physical processes are calculated. The final results

Stationary Solutions of Second-Order Equations for Fermions in Reissner–Nordström Space-Time
Autor: V. E. Shemarulin, I. I. Safronov, V. P. Neznamov
Publikováno v: Journal of Experimental and Theoretical Physics. 127:684-704
Existence of degenerate stationary bound states with square integrable radial wave functions was proved when second-order equations are used with the effective potential of the Reissner-Nordstr\"{o}m (RN) field with two event horizons for charged and

Motion of spin-half particles in the axially symmetric field of naked singularities of the static q-metric
Autor: V. P. Neznamov, V. E. Shemarulin
Publikováno v: Gravitation and Cosmology. 23:149-161
Quantum-mechanical motion of a spin-half particle is examined in the axially symmetric fields of static naked singularities formed by a mass distribution with a quadrupole moment (q-metric). The analysis is performed by means of the method of effecti

Classification of explicit three-stage symplectic difference schemes for the numerical solution of natural Hamiltonian systems: A comparative study of the accuracy of high-order schemes on molecular dynamics problems
Autor: V. E. Shemarulin, V. N. Sofronov
Publikováno v: Computational Mathematics and Mathematical Physics. 56:541-560
The natural Hamiltonian systems (systems with separable Hamiltonians) are considered. The variety of explicit three-stage symplectic schemes is described. A classification of the third-order accurate schemes is given. All fourth-order schemes are fou
