Global dynamical stability for KMS-states
Heide Narnhofer
The Hugenholz-Boltzmann-evolution is generalized to strongly interacting systems on the lattice. Under appropriate assumptions states stable under this evolution are shown to satif…

D-grading and quasifree evolution
Heide Narnhofer
Generalizing the relation between spin-systems and Fermi-systems on the lattice we construct for a spin-system with dimension d an algebra for which quasifree time-evolutions exist…

Cluster property and Bell's inequalities
F. Benatti, R. Floreanini, H. Narnhofer
Among the many loopholes that might be invoked to reconcile local realism with the experimental violations of Bell's inequalities, the space-dependence of the correlation functions…
