Temperature-Noise Interplay in a Coupled Model of Opinion Dynamics
Anna Chmiel, Julian Sienkiewicz
We consider a coupled system mimicking opinion formation under the influence of a group of neighbors (-lobby) that consists of an Ising part governed by temperature-like par…
q-neighbor Ising model on a polarized network
Anna Chmiel, Julian Sienkiewicz
In this paper, we examine the interplay between the lobby size in the -neighbor Ising model of opinion formation (Phys. Rev. E 92, 052105) and the level of overlap of tw…
A veritable zoology of successive phase transitions in the asymmetric -voter model on multiplex networks
Anna Chmiel, Julian Sienkiewicz, Agata Fronczak +1
We analyze a nonlinear -voter model with stochastic noise, interpreted in the social context as independence, on a duplex network. The size of the lobby (i.e., the pressure…
Truncated Lévy Walks and Superdiffusion in Boltzmann-Gibbs Equilibrium of the Hamiltonian Mean-Field Model
Piotr Fronczak, Agata Fronczak, Anna Chmiel +1
The Hamiltonian Mean-Field (HMF) model belongs to a broad class of statistical physics models with non-additive Hamiltonians that reveal many non-trivial properties, such as non-eq…
Tricriticality in the -neighbor Ising model on a partially duplex clique
Anna Chmiel, Julian Sienkiewicz, Katarzyna Sznajd-Weron
We analyze a modified kinetic Ising model, so called -neighbor Ising model, with Metropolis dynamics, [Phys. Rev. E 92, 052105], on a duplex clique and a partially duplex clique…
Growing spin model in deterministic and stochastic trees
Julian Sienkiewicz
We solve the growing asymmetric Ising model [Phys. Rev. E 89, 012105 (2014)] in the topologies of deterministic and stochastic (random) scale-free trees predicting its non-monotono…
