Identities for correlation functions in classical statistical mechanics and the problem of crystal states
David Ruelle
Let be the activity of point particles described by classical equilibrium statistical mechanics in . The correlation functions denote the probab…
Location of the Lee-Yang zeros and absence of phase transitions in some Ising spin systems
Joel L. Lebowitz, David Ruelle, Eugene R. Speer
We consider a class of Ising spin systems on a set Λof sites. The sites are grouped into units with the property that each site belongs to either one or two units, and the total in…
Phase transitions with four-spin interactions
Joel L. Lebowitz, David Ruelle
Using an extended Lee-Yang theorem and GKS correlation inequalities, we prove, for a class of ferromagnetic multi-spin interactions, that they will have a phase transition(and spon…
Nonequilibrium statistical mechanics and entropy production in a classical infinite system of rotators
David Ruelle
We analyze the dynamics of a simple but nontrivial classical Hamiltonian system of infinitely many coupled rotators. We assume that this infinite system is driven out of thermal eq…
Extending the definition of entropy to nonequilibrium steady states
David Ruelle
We study the nonequilibrium statistical mechanics of a finite classical system subjected to nongradient forces and maintained at fixed kinetic energy (Hoover-Evans isokinetic t…
