Abstract In this paper, we start reviewing the main features of the one-dimensional Ising model with long-range interactions, where the spin-spin coupling decays as a power law, J (r) r^- J (r) ∝ r - α. We then discuss the key properties of the one-dimensional voter model, in which two agents (spins) at distance r interact with a power-law probability with the same form of J (r). The two models are compared, and the so-called p -voter model is presented, which provides a framework to interpolate between them. Specifically, the p -voter model reduces to the voter model for p = 1 p = 1 and p = 2 p = 2, while for p 3 p ≥ 3 it falls into the universality class of the Ising model. Graphical abstract
