The scaling theory of type I superconductors close to the critical point is discussed. In this theory the exponent α = 0, which signals a heat capacity with a symmetric logarithmic divergence (non-classical behavior) superimposed on a discontinuity (classical behavior). An explicit scaling...

A nonlinear analysis based on Renyi entropy is applied to electromyography (EMG) time series from back muscles. The time dependence of the entropy of the EMG signal exhibits a crossover from a subdiffusive regime at short times to a plateau at longer times. We argue that this behavior...

A nonlinear dynamic model is constructed for the purpose of exploring the interaction between two conflicting political parties attempting to capture a share of the independent vote and prevail in elections or decisions. Party members influence the decisions to collaborate or not, either through...

We propose a "social physics" model for two-group conflict. We consider two disputing groups. Each individual in in each of the two groups has a preference si regarding the way in which the conflict should be resolved. The individual preferences span a range between M (prone to protracted...

This article draws on several research domains and disciplines –social psychology, models of complex systems, and planning scenario analysis – to propose a “toy” model of the dynamics of inter-group conflicts. The ingroup-outgroup conflict literature supports the notion that inside...

We extend a sociophysics model of two-group conflict dynamics to three groups. The model with attractors and chaos is proposed as a tool for exploring and managing intractable conflicts. It can be used to generate scenarios of trajectories and outcomes. We use mean-field theory for long-range...
