A solution of the Lane–Emden equation is obtained based on the approach developed for the Thomas–Fermi equation. The solution is obtained for small values of the independent variable. Based on the solution obtained, analytical expressions are sug

The wave function for the ground electron state in a dipole field is obtained based on the variational method. This function allows all the specific features of the examined system to be considered, for example, the impossibility of electron localiza

Upper and lower bounds on the second-order correction to the positronium ground-state energy due to the influence of the crystalline field in an ionic crystal are obtained, and the corresponding formulas are derived. The approximation adopted in the

We investigate the problem of loss of stability in an anharmonic atomic chain whose ends are subject to a constant tensile stress when we allow for interaction of not only immediate neighbors, but distant neighbors as well. Using the approximation of

This article presents a new method for closing infinite systems of equations for Green's functions. Its basis is a procedure for simultaneously splitting two higher-order Green's functions. There is a particular relationship between the three Green's

We investigate the role of Orbach-Aminov multistage phonon processes in nuclear spin-lattice relaxation via paramagnetic centers for ions with 1/2 spin in the absence of splitting by the crystal field.

A new approach is proposed for the transition to a rotating coordinate system under magic angle conditions. In contrast to the Redfield result, the obtained Hamiltonian contains additional secular terms differing from zero even for a magic angle. The
