Exact results for a generalized spin-1/2 Ising-Heisenberg diamond chain with the second-neighbor interaction between nodal spins
Bohdan Lisnyi, Jozef Strecka
The ground state and thermodynamics of a generalized spin-1/2 Ising-Heisenberg diamond chain with the second-neighbor interaction between nodal spins are calculated exactly using t…
Bath dynamics in an exactly solvable qubit model with initial qubit-environment correlations
V. V. Ignatyuk, V. G. Morozov
We study the bath dynamics in the dephasing model of a two-state quantum system (qubit) coupled to an environment of harmonic oscillators. This model was shown [Morozov et al., Phy…
Consistent description of kinetics and hydrodynamics of dusty plasma
B. Markiv, M. Tokarchuk
A consistent statistical description of kinetics and hydrodynamics of dusty plasma is proposed based on the Zubarev nonequilibrium statistical operator method. For the case of part…
Magnetization process, bipartite entanglement and enhanced magnetocaloric effect of the exactly solved spin-1/2 Ising-Heisenberg tetrahedral chain
Jozef Strecka, Onofre Rojas, Taras Verkholyak +1
The frustrated spin-1/2 Ising-Heisenberg ladder with Heisenberg intra-rung and Ising inter-rung interactions is exactly solved in a longitudinal magnetic field by taking advantage…
Consistent description of kinetics and hydrodynamics of weakly nonequilibrium processes in simple liquids
B. Markiv, I. Omelyan, M. Tokarchuk
The generalized transport equations for a consistent description of kinetic and hydrodynamic processes in dense gases and liquids are considered. The inner structure of the general…
Ferroelectric order parameter in the two-particle cluster system near phase transition point: collective variables method
M. A. Korynevskii, V. B. Solovyan
A new approach in the investigation of the order parameter behaviour near ferroelectric phase transition point is suggested. The short range and dipole interactions between particl…
Liquid-gas phase transition at and below the critical point
I. R. Yukhnovskii, V. O. Kolomiets, I. M. Idzyk
This article is a continuation of our previous works (see Yukhnovskii I.R. et al., J. Stat. Phys, 1995, 80, 405 and references therein), where we have described the behavior of a s…
Order parameter of a three-dimensional Ising-like system in the simplest and higher non-Gaussian approximations
I. V. Pylyuk
The application of the collective variables method to the study of the behaviour of nonuniversal characteristics of the system in the critical region is illustrated by an example o…
Low-temperature thermodynamics of spin-1/2 orthogonal-dimer chain with Ising and Heisenberg interactions
T. Verkholyak, J. Strecka
We consider an exactly solvable version of the quantum spin-1/2 orthogonal-dimer chain with the Heisenberg intra-dimer and Ising inter-dimer couplings. The investigated quantum spi…

Taras Verkholyak, Jozef Strecka
The quantum spin-1/2 orthogonal-dimer chain with the Heisenberg intra-dimer and Ising inter-dimer interactions in a magnetic field is considered by a rigorous approach. The model c…

A complete solution of the ground-state problem for an Ising model on the Shastry-Sutherland lattice with an additional interaction along the diagonals of "empty" squares in an app…
Phase transitions in the Potts model on complex networks
M. Krasnytska, B. Berche, Yu. Holovatch
The Potts model is one of the most popular spin models of statistical physics. The prevailing majority of work done so far corresponds to the lattice version of the model. However,…
Quantum transport equations for Bose systems taking into account nonlinear hydrodynamic processes
P. A. Hlushak, M. V. Tokarchuk
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 fluc…
