Social Physics: A manifesto
János Kertész, Marc Barthelemny, Marc Barthelemy +21
Social Physics seeks quantitative, empirically testable explanations of collective human behavior. Its name has a long and contested history, but its contemporary program is neithe…
The Lee-Yang property of the Blume-Capel model
Yuri Kozitsky, Yurij Holovatch
The Lee-Yang theory is based on the theorem concerning a property of the ferromagnetic Ising model partition function proved by T. D. Lee and C. N. Yang in 1952. It provides powerf…
Staggering domino-like blast front motion in a one-dimensional cold gas
Taras Holovatch, Yuri Kozitsky, Krzysztof Pilorz +1
One-dimensional alternating particle systems are widely used to study interconnections between the hydrodynamics of blast waves in a gas-like medium and the Newtonian dynamics of i…
100 Glorious Years of the Ising Model
Muktish Acharyya, Yurij Holovatch, Ferenc Igloi
This is an editorial article based on the reseaches on the Ising model over the last 100 years.
Breakdown of hydrodynamics in a one-dimensional cold gas
Taras Holovatch, Yuri Kozitsky, Krzysztof Pilorz +1
The following model is studied analytically and numerically: point particles with masses () are distributed over the positive half-axis. Their dynamics is in…
Effective and asymptotic scaling in a one-dimensional billiard problem
T. Holovatch, Yu. Kozitsky, K. Pilorz +1
The emergence of power laws that govern the large-time dynamics of a one-dimensional billiard of point particles is analysed. In the initial state, the resting particles are pl…
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…
Collective decision-making with heterogeneous biases: Role of network topology and susceptibility
Yunus Sevinchan, Petro Sarkanych, Abi Tenenbaum +2
The ability of groups to make accurate collective decisions depends on a complex interplay of various factors, such as prior information, biases, social influence, and the structur…
On the shape of Gaussian scale-free polymer networks
V. Blavatska, Yu. Holovatch
We consider the model of complex hyperbranched polymer structures formed on the basis of scale-free graphs, where functionalities (degrees) of nodes obey a power law decaying p…
Julian Hirniak, an early proponent of periodic chemical reaction
Niklas Manz, Yurij Holovatch, John Tyson
In this article we present and discuss the work and scientific legacy of Julian Hirniak, the Ukrainian chemist and physicist who published two articles in 1908 and 1911 about perio…
Ising's roots and the transfer-matrix eigenvalues
Reinhard Folk, Yurij Holovatch
Today, the Ising model is an archetype describing collective ordering processes. And, as such, it is widely known in physics and far beyond. Less known is the fact that the thesis…
Critical and tricritical singularities from small-scale Monte Carlo simulations: The Blume-Capel model in two dimensions
Leïla Moueddene, Nikolaos G Fytas, Yurij Holovatch +2
We show that the study of critical properties of the Blume-Capel model at two dimensions can be deduced from Monte Carlo simulations with good accuracy even for small system sizes…
The diaspora model for human migration
Rafael Prieto-Curiel, Ola Ali, Elma Dervic +5
Migration's impact spans various social dimensions, including demography, sustainability, politics, economy and gender disparities. Yet, the decision-making process behind migrants…
Shape analysis of random polymer networks
V. Blavatska, K. Haydukivska, Yu. Holovatch
We analyze conformational properties of branched polymer structures, formed on the base of Erdös-Rényi random graph model. We consider networks with vertices and variable par…
Classical phase transitions in a one-dimensional short-range spin model induced by entropy depletion or complex fields
Petro Sarkanych, Yurij Holovatch, Ralph Kenna
Ising's solution of a classical spin model famously demonstrated the absence of a positive-temperature phase transition in one-dimensional equilibrium systems with short-range inte…
The Fate of Ernst Ising and the Fate of his Model
Thomas Ising, Reinhard Folk, Ralph Kenna +2
On this, the occasion of the 20th anniversary of the "Ising Lectures" in Lviv (Ukraine), we give some personal reflections about the famous model that was suggested by Wilhelm Lenz…
Complex systems: physics beyond physics
Yurij Holovatch, Ralph Kenna, Stefan Thurner
Complex systems are characterized by specific time-dependent interactions among their many constituents. As a consequence they often manifest rich, non-trivial and unexpected behav…
Academic research groups: evaluation of their quality and quality of their evaluation
Bertrand Berche, Yurij Holovatch, Ralph Kenna +1
In recent years, evaluation of the quality of academic research has become an increasingly important and influential business. It determines, often to a large extent, the amount of…
Partition function zeros for the Ising model on complete graphs and on annealed scale-free networks
M. Krasnytska, B. Berche, Yu. Holovatch +1
We analyze the partition function of the Ising model on graphs of two different types: complete graphs, wherein all nodes are mutually linked and annealed scale-free networks for w…
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,…
Modeling Metropolis Public Transport
C. von Ferber, T. Holovatch, Yu. Holovatch +1
We present results of a survey of public transport networks (PTNs) of selected 14 major cities of the world with PTN sizes ranging between 2000 and 46000 stations and develop an ev…
