On the two- and three-dimensional Lenz-Ising-Onsager problem in presence of magnetic field
Martin S. Kochman'ski
In this paper a new approach to solving the Ising-Onsager problem in external magnetic field is investigated. The expression for free energy on one Ising spin in external field bot…

Jordan-Wigner transformations and their generalizations for multidimensional systems
Martin S. Kochman'ski
In the paper nonlinear transformations of the Jordan-Wigner (JW) type are introduced in the form different from the ones known previously, for the purpose of expressing multi-index…

Low-temperature asymptotics of free energy of 3D Ising model in an external magnetic field
Martin S. Kochman'ski
The paper presents new method for calculating the low-temperature asymptotics of free energy of the 3D Ising model in external magnetic field . The results obtained are…
