Local Primitive Causality and the Common Cause Principle in Quantum Field Theory
Miklos Redei, Stephen J. Summers
If \{A(V)\} is a net of local von Neumann algebras satisfying standard axioms of algebraic relativistic quantum field theory and V_1 and V_2 are spacelike separated spacetime regio…

Transplantation of Local Nets and Geometric Modular Action on Robertson-Walker Space-Times
Detlev Buchholz, Jens Mund, Stephen J. Summers
A novel method of transplanting algebras of observables from de Sitter space to a large class of Robertson-Walker space-times is exhibited. It allows one to establish the existence…

An Algebraic Characterization of Vacuum States in Minkowski Space. II. Continuity Aspects
Detlev Buchholz, Martin Florig, Stephen J. Summers
An algebraic characterization of vacuum states in Minkowski space is given which relies on recently proposed conditions of geometric modular action and modular stability for algebr…
