Heider balance of a chain of actors as dependent on the interaction range and a thermal noise

Abstract

The Heider balance is investigated in a chain of actors, with periodic boundary conditions and the neighborhood of range , with as a parameter. Two model dynamics are applied: a deterministic cellular automaton (Malarz et al, Physica D 411 (2020) 132556) and the heat-bath algorithm, with the density of unbalanced-balanced triads in the role of energy. The outcome is a spectrum of energy in stationary and blinking states and a balanced-unbalanced network transition driven by thermal noise. The critical point increases with the range and it does not depend on the system size.
