Phase transitions associated with economy and demography [PDF]
Компьютерные исследования и моделирование, 2010 Crises in social systems are considered by analogy with phase transitions and the corresponding critical phenomena in «non-living» many-particle physical systems.

Transitional Channel Flow: A Minimal Stochastic Model
Entropy, 2020 In line with Pomeau’s conjecture about the relevance of directed percolation (DP) to turbulence onset/decay in wall-bounded flows, we propose a minimal stochastic model dedicated to the interpretation of the spatially intermittent regimes observed in ...

Вестник Дагестанского государственного технического университета: Технические науки, 2016 Using Monte-Carlo simulations, we investigated phase transitions and frustrations in the three-state Potts model on a triangular lattice with allowance for antiferromagnetic exchange interactions between nearest- neighbors J1 and next- nearest- neighbors

Critical phenomena in exponential random graphs [PDF]
, 2013 The exponential family of random graphs is one of the most promising class of network models. Dependence between the random edges is defined through certain finite subgraphs, analogous to the use of potential energy to provide dependence between particle

Critical phenomena for systems under constraint
Condensed Matter Physics, 2014 It is well known that the imposition of a constraint can transform the properties of critical systems. Early work on this phemomenon by Essam and Garelick, Fisher, and others, focused on the effects of constraints on the leading critical exponents ...

Critical Phenomena Associated with Boson Stars [PDF]
, 2001 We present a brief synopsis of related work (gr-qc/0007039), describing a study of black hole threshold phenomena for a self-gravitating, massive complex scalar field in spherical symmetry.

Critical phenomena in active matter [PDF]
Physical Review E, 2016 We investigate the effect of self-propulsion on a mean-field order-disorder transition. Starting from a $ ^4$ scalar field theory subject to an exponentially correlated noise, we exploit the Unified Colored Noise Approximation to map the non-equilibrium active dynamics onto an effective equilibrium one.

Critical phenomena in ferromagnetic antidot lattices
AIP Advances, 2016 In this paper a quantitative theoretical formulation of the critical behavior of soft mode frequencies as a function of an applied magnetic field in two-dimensional Permalloy square antidot lattices in the nanometric range is given according to ...
