On the zero-temperature limit of Gibbs states

arXiv:0907.0081 · doi:10.1007/s00220-010-0997-8

Abstract

We exhibit Lipschitz (and hence Hölder) potentials on the full shift such that the associated Gibbs measures fail to converge as the temperature goes to zero. Thus there are "exponentially decaying" interactions on the configuration space for which the zero-temperature limit of the associated Gibbs measures does not exist. In higher dimension, namely on the configuration space , , we show that this non-convergence behavior can occur for finite-range interactions, that is, for locally constant potentials.

The statement of Theorem 1.2 is more accurate and some new comment follow it
