Topological quantum correction to an atomic ideal gas law as a dark energy effect
Eugene V. Kholopov
The traditional ambiguity about the bulk electrostatic potentials in crystals is due to the conditional convergence of Coulomb series. The classical Ewald approach turns out to be…
Convergence peculiarities of lattice summation upon multiple charge spreading generalizing the Bertaut approach
Eugene V. Kholopov
Within investigating the multiple charge spreading generalizing the Bertaut approach, a set of confined spreading functions with a polynomial behaviour, but defined so as to enhanc…
Multiple charge spreading as a generalization of the Bertaut approach to lattice summation of Coulomb series in crystals
Eugene V Kholopov
The Bertaut approach associated with charge spreading so as to enhance the rate of convergence of Coulomb series in crystals is extended to the case of an arbitrary multiple spread…
Spherical spin-orientation degeneracy of basic antiferromagnetic configurations due to the dipolar interaction in cubic lattices
Eugene V. Kholopov
Based on a simple general relation for the Lorentz field, the precise values are obtained for the energies of ferromagnetic and basic antiferromagnetic states in sc, bcc, fcc, and…
Pyroelectric vector and related polarization effects
Eugene V. Kholopov
The principal fact that the pyroelectric vector $\Pb^0$ typical of polar crystals is invisible in equilibrium has been verified. Nevertheless, the general formula for $\Pb^0$ as a…
Local lattice potentials and steady-state vacancies in ionic crystals
Eugene V. Kholopov
Basing on peculiarities of local potentials, the two principal trends in vacancy formation are revealed. The proximity to the threshold of local ionic stability due to a giant pote…
