New method to obtain the interaction Hamiltonian of phonons at superfluid helium - solid interface is proposed in the work. Equations of hydrodynamic variables are obtained in terms of second quantization if helium occupies ...

How attention scarcity effects the outcomes of a game? We present our findings on a version of the Iterated Prisoners Dilemma (IPD) game in which players can accept or refuse to play with their partner. We study the memory ...

Lagrangian of electronic liquid in magneto-inhomogeneous micro-conductor has been constructed. A corresponding Euler-Lagrange equation has been solved. It was shown that the described system has eigenmodes of spin polarization ...

A dependence of a relaxation rate on the shape of the demagnetized region for a longitudinal evolution of total magnetization to its equilibrium value following the ultrafast demagnetization is demonstrated. This ...

The nature of long-range interactions between dust grains in plasma is discussed. The dust grain interaction potential within a cell model of dusty plasma is introduced. The attractive part of inter-grain potential is ...

May 15 this year was the 60th birthday of Mykola Lebovka, an outstanding Ukrainian scientist in the field of physical chemistry of condensed matter, Doctor Habilitus in Physics and Mathematics, professor, head of the ...

Non-linear theory of diffusion of impurities in porous materials upon ultrasonic treatment is described. It is shown that at a defined value of deformation amplitude, an average concentration of vacancies and temperature ...

Explicit expression for the N-point free energy distribution function in one dimensional directed polymers in a random potential is derived in terms of the Bethe ansatz replica technique. The obtained result is equivalent ...

The sensitivity of the wavelength position of the surface plasmon resonances in a prolate and oblate fine metal particles to the refractive index of an embedding solution, a particle shape, and electron temperature is ...

Using the method of nonequilibrium statistical operator by Zubarev, an approach is proposed for the description of kinetics which takes into account the nonlinear hydrodynamic fluctuations for a quantum Bose system. ...
