A mathematical theory of the critical point of ferromagnetic Ising systems
Domingos H. U. Marchetti, Manfred Requardt, Walter F. Wreszinski
We develop a theory of the critical point of the ferromagnetic Ising model, whose basic objects are the ergodic (pure) states of the infinite system. It proves the existence of ano…
A theory of quantum (statistical) measurement
Walter F. Wreszinski
We propose a theory of quantum (statistical) measurement which is close, in spirit, to Hepp's theory, which is centered on the concepts of decoherence and macroscopic (classical) o…
The second law of thermodynamics as a deterministic theorem for quantum spin systems
Walter F. Wreszinski
We review our approach to the second law of thermodynamics, viewed as a theorem asserting the growth of the mean (Gibbs-von Neumann) entropy of quantum spin systems undergoing auto…
Perturbative versus non-perturbative quantum field theory: the method of Tao, the Casimir effect and interacting Wightman theories
Walter F. Wreszinski
We dwell upon certain points concerning the meaning of quantum field theory, among these the problems with the perturbative approach, and the question raised by tHooft of the exist…
A relation of thermodynamic relevance between the superadditivity, concavity and homogeneity properties of real-valued functions
Walter F. Wreszinski
We provide a necessary and sufficient condition for the validity of the following Landsberg-Thirring theorem: for a real-valued function on a convex set, any two of the properties…
Unstable states in a model of nonrelativistic quantum electrodynamics: corrections to the Lorentzian distribution
Walter F. Wreszinski
We review the Lee-Friedrichs model as a model of atomic resonances in the hydrogen atom, using the dipole-moment matrix-element functions which have been exactly computed by Nussen…
