Voter Model with Surface Tension — •Bruno Pace and Konstantin Klemm — Leipzig University

Spin systems are very central in the context of Statistical Physics for their simplicity and generality. But also, any process out of the realm of physics that shares some intrinsic properties and symmetries with these models will inherit some of their characteristics like the phase transitions or scaling properties.

There is a well-known comparison between the Voter model and the Ising model at zero temperature. In the latter, however, curvature-driven surface tension orders the system. Here we propose a different microscopic mechanism inspired in the classic Voter dynamics for the emergence of a surface tension. It consists of making the agents actively persuasive: after choosing one node of the network, it will try to interact only with different state neighbours. Some characteristics of the out of equilibrium dynamics are explored.
