The boundary conditions are obtained for NS interface at the presence of arbitrary concentrations of nonmagnetic impurities. The current states in SNS junction are considered. The solution obtained for the current ...

The path integral formalism is used to describe the statistical properties of an ideal gas of spinless particles. It is shown that the quantum paths exhibit the same properties in non-relativistic and relativistic domains ...

The present and the preceding issues of “Condensed Matter Physics” contain papers written in honour of Professor Ihor Yukhnovskii on the occasion of his 75th birthday. Professor Ihor Yukhnovskii is a well-known Ukrainian ...

In this paper we construct a mathematical model of securities market. The results obtained are a good basis for an analysis of any stock market.

For theoretical description of pseudospin systems with essential short-range and long-range interactions we use the method based on calculations of the free energy functional taking into account the short-range interactions ...

How much fuel remained inside the Chornobyl Unit 4 after the accident? What is the scale of radionuclide emission in the environment? Till now these questions excite the scientific community of the world. The critical analysis ...

Ionic association in electrolyte solutions is investigated in the framework of chemical models. The associative mean spherical approximation (AMSA) for electrolyte theory is reviewed. It is shown that AMSA in combination with ...
