Partition function zeros for the Blume-Capel model on a complete graph
Yulian Honchar, Mariana Krasnytska, Bertrand Berche +2
In this paper we study finite-size effects in the Blume-Capel model through the analysis of the zeros of the partition function. We consider a complete graph and make use of the be…
Ising model with varying spin strength on a scale-free network: scaling functions and critical amplitude ratios
M. Krasnytska
Recently, a novel model to describe ordering in systems comprising agents which, although matching in their binarity (i.e., maintaining the iconic Ising features of ``+'' or ``-'',…
Individual bias and fluctuations in collective decision making: from algorithms to Hamiltonians
Petro Sarkanych, Mariana Krasnytska, Luis Gómez-Nava +2
In this paper, we reconsider the spin model suggested recently to understand some features of collective decision making among higher organisms [A.T. Hartnett et al., Phys. Rev. Le…
Potts Model with Invisible States: A Review
Mariana Krasnytska, Petro Sarkanych, Bertrand Berche +2
The Potts model with invisible states was introduced to explain discrepancies between theoretical predictions and experimental observations of phase transitions in some systems whe…
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…
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…
Generalized Ising Model on a Scale-Free Network: An Interplay of Power Laws
Mariana Krasnytska, Bertrand Berche, Yurij Holovatch +1
We consider a recently introduced generalization of the Ising model in which individual spin strength can vary. The model is intended for analysis of ordering in systems comprising…
Network of scientific concepts: empirical analysis and modeling
Vasyl Palchykov, Mariana Krasnytska, Olesya Mryglod +1
Concepts in a certain domain of science are linked via intrinsic connections reflecting the structure of knowledge. To get a qualitative insight and a quantitative description of t…
A mechanism for evolution of the physical concepts network
V. Palchykov, M. Krasnytska, O. Mryglod +1
We suggest an underlying mechanism that governs the growth of a network of concepts, a complex network that reflects the connections between different scientific concepts based on…
Ising model with variable spin/agent strengths
Mariana Krasnytska, Bertrand Berche, Yurij Holovatch +1
We introduce varying spin strengths to the Ising model, a central pillar of statistical physics. With inhomogeneous physical systems in mind, but also anticipating interdisciplinar…
Ising model with invisible states on scale-free networks
Petro Sarkanych, Mariana Krasnytska
We consider the Ising model with invisible states on scale-free networks. Our goal is to investigate the interplay between the entropic and topological influence on a phase transit…
Violation of Lee-Yang circle theorem for Ising phase transitions on complex networks
M. Krasnytska, B. Berche, Yu. Holovatch +1
The Ising model on annealed complex networks with degree distribution decaying algebraically as has a second-order phase transition at finite temperature if $λ> 3…
Scaling functions and amplitude ratios for the Potts model on an uncorrelated scale-free network
M. Krasnytska
We study the critical behaviour of the -state Potts model on an uncorrelated scale-free network having a power-law node degree distribution with a decay exponent . Previous d…
