TY - RPRT TI - Non-unicity of Gibbs states of Czech models in a half-space AB - A classical lattice model is studied yielding a unique state in the bulk but featuring at least two equilibrium states once considered in a half-space. The properties of the two states are discussed. In particular, the cluster expansion method is used to evaluate their difference deep in the bulk away from the boundary of the half-space.
