Quasi-Exactly Solvable Potentials with Three Known Eigenstates
T. V. Kuliy, V. M. Tkachuk
We propose a new SUSY method for construction of the quasi-exactly solvable (QES) potentials with three known eigenstates. New QES potentials and corresponding energy levels and wa…

Magnetic Properties of Dilute Alloys: Equations for Magnetization and its Structural Fluctuations
I. Vakarchuk, V. Tkachuk, T. Kuliy
The dilute Heisenberg ferromagnet is studied taking into account fluctuations of magnetization caused by disorder. A self-consistent system of equations for magnetization and its m…

The influence of structure disorder on mean atomic momentum fluctuations and a spin-wave spectrum
I. Vakarchuk, V. Tkachuk, T. Kuliy
The relation between atomic momenta fluctuations and density fluctuations is obtained in frames of mean-field approximation. Using two-time temperature Green functions within Tyabl…
