We compare the dynamical characterization of pure thermodynamical phases as extremal
KMS states and their characterization as extremal time‐ or space‐invariant states. We find that…

The fixed point structure resulting from the approximate renormalization group equations
obtained by shifting bonds on the square Ising lattice is considered as a function of a free …

We investigate a 19-vertex version of the two-dimensional fully frustrated XY (FFXY) model.
We construct Yang-Baxter equations for this model and show that there is no solution. …

An exact relation is established between the solid-on-solid model describing the growth of
crystals and the classical XY model. Application of this relation to a special case leads to an …

The dynamic scaling properties of a polycrystalline growth model proposed by Van der Drift
are discussed. We present an analytic derivation of the dynamic exponent, describing the …

A new and more direct derivation is given of an extended set of renormalization equations
for the two-dimensional Coulomb gas. Our equations are equivalent to those proposed by …

We study the dynamics of an incommensurate chain sliding on a periodic lattice, modeled by
the Frenkel-Kontorova Hamiltonian with initial kinetic energy, without damping and driving …

A Kadanoff lower-bound renormalization transformation with three variational parameters
has been applied to the Blume-Capel model by Burkhardt. We report some additional results …

This paper studies the nonequilibrium energetics of growth steps. It discusses the energy
and free energy of a [100] step on a Kossel (001) crystal surface as a function of the driving …

In this paper a general and simple method to calculate exactly the critical temperature for
Ising nets on periodic structures is introduced. The method can be used to predict the …
