Title. Non-convergence of equilibrium states at zero temperature limit
Abstract.
We construct finite-range interactions on a two dimensional symbolic dynamical system, for which the associated equilibrium states (i.e., the shift-invariant Gibbs states) fail to converge as temperature goes to zero. More precisely, if we pick any one-parameter family of equilibrium states at inverse temperature for this interaction, then the limit does not exist. This settles a question posed by Chazottes and Hochman who obtained such a non-convergence behavior when dimension greater than 3.
