Bell inequality and common causal explanation in algebraic quantum field theory
Gábor Hofer-Szabó, Péter Vecsernyés
Bell inequalities, understood as constraints between classical conditional probabilities, can be derived from a set of assumptions representing a common causal explanation of class…

Noncommuting local common causes for correlations violating the Clauser-Horne inequality
Gábor Hofer-Szabó, Péter Vecsernyés
In the paper the EPR-Bohm scenario will be reproduced in an algebraic quantum field theoretical setting with locally finite degrees of freedom. It will be shown that for a set of s…

Noncommutative Common Cause Principles in Algebraic Quantum Field Theory
Gábor Hofer-Szabó, Péter Vecsernyés
States in algebraic quantum field theory "typically" establish correlation between spacelike separated events. Reichenbach's Common Cause Principle, generalized to the quantum fiel…
