Peculiarities of oscillator with nonlinear cordinate-dependent mass
B. I. Lev, V. B. Tymchyshyn, A. G. Zagorodny
A nonlinear model of the scalar field with a coupling between the field and its gradient is developed. It is shown, that such model is suitable for the description of phase transit…

Free energy analysis for a system of interacting particles arranged in Bravais lattice
B. I. Lev, V. B. Tymchyshyn, A. G. Zagorodny
We propose a method of free energy calculation for a system of interacting particles arranged in a Bravais lattice. It will be shown how to treat divergences for infinite unbounded…
