The pressure (stress) is assumed small but positive and bounded away from zero, while the temperature goes to zero. Our main results are: (1) As _x000C_ the temperature goes to zero and at fixed positive pressure, the Gibbs measures _x0016__x000C_for infinite chains and semi-infinite chains satisfy path large deviations principles. The rate functions are bulk and surface energy functionals. The minimizer of the surface functional corresponds to zero temperature boundary layers. (2) The surface correction to the Gibbs free energy converges to the zero temperature surface energy, characterized with the help of the minimum of the surface energy functional. (3) The bulk Gibbs measure and Gibbs free energy can be approximated by their Gaussian counterparts. (4) Bounds on the decay of correlations are provided, some of them uniform in _x000C_the inverse temperature.eng510Atomistic models of elasticitysurface energy and boundary layerssemi-classical limit of transfer operatorsuniform decay of correlationspath large deviations forstationary processesReport57 S.
