Subsystems and Independence in Relativistic Microscopic Physics
Stephen J. Summers
The analyzability of the universe into subsystems requires a concept of the "independence" of the subsystems, of which the relativistic quantum world supports many distinct notions…
When are quantum systems operationally independent?
Miklos Redei, Stephen J. Summers
We propose some formulations of the notion of "operational independence" of two subsystems of a larger quantum system and clarify their relation to other independence concepts in t…
Quantum Probability Theory
Miklos Redei, Stephen J. Summers
The mathematics of classical probability theory was subsumed into classical measure theory by Kolmogorov in 1933. Quantum theory as nonclassical probability theory was incorporated…
Quantum statistics and locality
Detlev Buchholz, Stephen J. Summers
It is shown that two observers have mutually commuting observables if they are able to prepare in each subsector of their common state space some state exhibiting no mutual correla…
Remarks on Causality in Relativistic Quantum Field Theory
Miklos Redei, Stephen J. Summers
It is shown that the correlations predicted by relativistic quantum field theory in locally normal states between projections in local von Neumann algebras $\cA(V_1),\cA(V_2)$ asso…
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…
