Negative/positive electrocaloric effect in antiferroelectric squaric acid
A. P. Moina
Using the previously developed model we study the electrocaloric effect (ECE) in antiferroelectric crystals of squaric acid. At low temperatures, the polarization reorientation by…
One for all and all for one: on the role of a conference in a scientist's life
Olesya Mryglod
The quantitative description of the scientific conference MECO (Middle European Cooperation in Statistical Physics) based on bibliographic records is presented in the paper. Statis…
Thermal first-order phase transitions, Ising critical points, and reentrance in the Ising-Heisenberg model on the diamond-decorated square lattice in a magnetic field
Jozef Strecka, Katarina Karlova, Taras Verkholyak +3
The thermal phase transitions of a spin-1/2 Ising-Heisenberg model on the diamond-decorated square lattice in a magnetic field are investigated using a decoration-iteration transfo…
Peculiarities of gender disambiguation and ordering of non-English authors' names for Economic papers beyond core databases
O. Mryglod, S. Nazarovets, S. Kozmenko
This paper presents the results of further exploration of Crossref data related to Ukrainian Economics research (the first part can be found in [Mryglod, O., Nazarovets, S. & Kozme…
Contact theorems for anisotropic fluids near a hard wall
M. Holovko, D. di Caprio
In this paper, starting from the Born-Green-Yvon (BGY) equation, we derive a general expression for the contact value of the singlet distribution function near a hard wall for anis…
Potts model with invisible states on a scale-free network
P. Sarkanych, M. Krasnytska
Different models are proposed to understand magnetic phase transitions through the prism of competition between the energy and the entropy. One of such models is a -state Potts…
Effects of porous media on the phase behaviour of polypeptide solutions
V. I. Shmotolokha, M. F. Holovko
The generalized van der Waals equation for anisotropic fluids in porous media, proposed by the authors in previous works, is used to describe the effect of porous media on the phas…
On the algorithm to perform Monte Carlo simulations in cells with constant volume and variable shape
A. Baumketner
In simulations of crystals, unlike liquids or gases, it may happen that the properties of the studied system depend not only on the volume of the simulation cell but also on its sh…
Phases of the spin-1/2 Heisenberg antiferromagnet on the diamond-decorated square lattice in a magnetic field
Nils Caci, Katarina Karlova, Taras Verkholyak +3
The spin-1/2 Heisenberg antiferromagnet on the frustrated diamond-decorated square lattice is known to feature various zero-field ground-state phases, consisting of extended monome…
On the new universality class in structurally disordered -vector model with long-range interactions
Dmytro Shapoval, Maxym Dudka, Yurij Holovatch
We study a stability border of a region where nontrivial critical behaviour of an -vector model with long-range power-law decaying interactions is induced by the presence of a s…
Effective and asymptotic criticality of structurally disordered magnets
Maxym Dudka, Mariana Krasnytska, Juan J. Ruiz-Lorenzo +1
Changes in magnetic critical behaviour of quenched structurally-disordered magnets are usually exemplified in experiments and in MC simulations by diluted systems consisting of mag…
Fluid-fluid phase behaviour in the explicit solvent ionic model: hard spherocylinder solvent molecules
M. Hvozd, T. Patsahan, O. Patsahan +1
We study a fluid-fluid phase transition of the explicit solvent model represented as a mixture of the restricted primitive model (RPM) of ionic fluid and neutral hard spherocylinde…
Charge and electric field distributions in the interelectrode region of an inhomogeneous solid electrolyte
I. Kravtsiv, G. Bokun, M. Holovko +2
A solid ionic conductor with cation conductivity in the interelectrode region is studied. Due to their large size, the anions are considered fixed and form a homogeneous neutralizi…
Effect of hydrostatic pressure on dynamic dielectric characteristics of CsHPO ferroelectric
A. S. Vdovych, I. R. Zachek, R. R. Levitskii
Based on the pseudospin model of the deformed CsHPO crystal within the Glauber method, the equation for the time-dependent mean value of the pseudospin is obtained, which i…
Quantum Heisenberg model on a sawtooth-chain lattice: Rotation-invariant Green's function method
Taras Hutak, Taras Krokhmalskii, Oleg Derzhko +1
We apply the rotation-invariant Green's function method (RGM) to study the spin Heisenberg model on a one-dimensional sawtooth lattice, which has two nonequivalent sites in…
Survival in two-species reaction-superdiffusion system: Renormalization group treatment and numerical simulations
Dmytro Shapoval, Viktoria Blavatska, Maxym Dudka
We analyze the two-species reaction-diffusion system including trapping reaction as well as coagulation/annihilation reactions where particles of bo…
Structural aspects of the clustering of curcumin molecules in water. Molecular dynamics computer simulation study
T. Patsahan, O. Pizio
We explore clustering of curcumin molecules in water by using the OPLS-UA model for the enol conformer of curcumin (J. Mol. Liq., 223, 707, 2016) and the SPC-E water model. With th…
