Critical behaviour of a 3D Ising-like system in the ρ^6 model approximation: Role of the correction for the potential averaging
I. V. Pylyuk, M. V. Ulyak
The critical behaviour of systems belonging to the three-dimensional Ising universality class is studied theoretically using the collective variables (CV) method. The partition fun…
Zubarev nonequilibrium statistical operator method in Renyi statistics. Reaction-diffusion processes
P. Kostrobij, R. Tokarchuk, M. Tokarchuk +1
The Zubarev nonequilibrium statistical operator (NSO) method in Renyi statistics is discussed. The solution of -parametrized Liouville equation within the NSO method is obtained…
A non-classical van der Waals loop: Collective variables method
R. V. Romanik, M. P. Kozlovskii
The equation of state is investigated for an Ising-like model in the framework of collective variables method. The peculiar feature of the theory is that a non-classical van der Wa…
The method of collective variables: a link with the density functional theory
O. Patsahan, I. Mryglod
Recently, based on the method of collective variables the statistical field theory for multicomponent inhomogeneous systems was formulated [O. Patsahan, I. Mryglod, J.-M. Caillol,…
Marginal dimensions for multicritical phase transitions
M. Dudka, R. Folk, Yu. Holovatch +1
The field-theoretical model describing multicritical phenomena with two coupled order parameters with n_{||} and n_{\perp} components and of O(n_{||}) \oplus O(n_{\perp}) symmetry…
Phase transitions and dynamical properties of quasi-one-dimensional structures with hydrogen bonds
R. Ya. Stetsiv
The frequency dependence of dynamical conductivity of the quasi-one-dimensional structures with hydrogen bonds is studied on the basis of pseudospin-electron model. It takes into a…
Flat-Band Ferromagnetism as a Pauli-Correlated Percolation Problem
M. Maksymenko, A. Honecker, R. Moessner +2
We investigate the location and nature of the para-ferro transition of interacting electrons in dispersionless bands using the example of the Hubbard model on the Tasaki lattice. T…
Quantum phase transitions in the exactly solved spin-1/2 Heisenberg-Ising ladder
Taras Verkholyak, Jozef Strecka
Ground-state behaviour of the frustrated quantum spin-1/2 two-leg ladder with the Heisenberg intra-rung and Ising inter-rung interactions is examined in detail. The investigated mo…
A temperature behavior of the frustrated translational mode of adsorbate and the nature of the "adsorbate-substrate" interaction
V. V. Ignatyuk
A temperature behavior of the frustrated translational mode (T-mode) of a light particle, coupled by different regimes of ohmicity to the surface, is studied within a formalism of…
Gibbs free energy and Helmholtz free energy for a three-dimensional Ising-like model
M. P. Kozlovskii, R. V. Romanik
The critical behavior of a 3D Ising-like system is studied at the microscopic level of consideration. The free energy of ordering is calculated analytically as an explicit function…
Viscoelastic description of electron subsystem of a semi-bounded metal within generalized "jellium" model
P. P. Kostrobij, B. M. Markovych, A. I. Vasylenko +1
Viscoelastic description of the electron subsystem of a semi-bounded metal on the basis of the generalized "jellium" model using the method of nonequilibrium statistical Zubarev op…
Statistical Description of Hydrodynamic Processes in Ionic Melts with taking into account Polarization Effects
B. Markiv, A. Vasylenko, M. Tokarchuk
Statistical description of hydrodynamic processes for ionic melts is proposed with taking into account polarization effects caused by the deformation of external ionic shells. This…
Effect of mesoscopic fluctuations on equation of state in cluster-forming systems
Alina Ciach, Oksana Patsahan
Equation of state for systems with particles self-assembling into aggregates is derived within a mesoscopic theory combining density functional and field-theoretic approaches. We f…
