Reality, measurement and locality in Quantum Field Theory
Quantum Field Theory Standard Model Correlations Locality
2008/4/22
It is currently believed that the local causality of Quantum Field
Theory (QFT) is destroyed by the measurement process. This belief
is also based on the Einstein-Podolsky-Rosen (EPR) paradox and on...
In defence of naivete: The conceptual status of Lagrangian quantum field theory
Quantum field theory QFT
2008/4/14
I analyse the conceptual and mathematical foundations of
Lagrangian quantum field theory (that is, the "naive" quantum field theory used in mainstream physics, as opposed to algebraic quantum field ...
This paper explores various functions of idealizations in quantum field theory. To this end it is important to first distinguish between different kinds of theories and models of or inspired by quantu...
Generating Ontology: From Quantum Mechanics to Quantum Field Theory
quantum field theory particle physics
2008/4/14
Philosophical interpretations of theories generally presuppose that a theory can be presented as a consistent mathematical formulation that is interpreted through models. Algebraic quantum field theor...
This contribution gives an overview of Einstein's work on unified field theory. It characterizes this work from four perspectives, by looking at its conceptual, representational, biographical, and phi...
Are Rindler Quanta Real? Inequivalent Particle Concepts in Quantum Field Theory
quanta Minkowski Rindler Weyl Algebra
2008/4/10
Philosophical reflection on quantum field theory has tended to focus on how it revises our conception of
what a particle is. However, there has been relatively little discussion of the threat to the ...
Field theories have been central to physics over the last 150 years, and there are several theories in contemporary physics in which physical fields play key causal and explanatory roles. This paper p...
