14. Mai 2023 · This year’s workshop will explore four broad philosophical issues that are specific to QFT. QFT is the theory that combines the special theory of relativity and quantum mechanics. There is consensus that the unification of these two theories necessitates the use of a mathematical framework based on fields. One issue that this raises is how to ...
3. Mai 2021 · But many if not most papers classified under ‘Particles and Fields’, ‘Symmetry and Invariance’ and ‘Condensed Matter Physics’ concern quantum theories. So when correcting for these two considerations, we arguably shall still reach the conclusion that quantum theories form the biggest sub-branch of philosophy of physics (at least 60% ...
22. Juni 2006 · Quantum Field Theory. Quantum Field Theory (QFT) is the mathematical and conceptual framework for contemporary elementary particle physics. In a rather informal sense QFT is the extension of quantum mechanics (QM), dealing with particles, over to fields, i.e. systems with an infinite number of degrees of freedom.
freedom. A quantum theory of a system with infinitely many degrees of freedom is a quantum field theory. We use the term quantum the-ory to embrace both quantum-mechanical theories and quantum field theories. 2.1 Constructing quantum theories To construct a quantum theory, one identifies a system or systems of
The focus of this work is on conceptual issues, on the clarification of the foundations of quantum field theory, and ultimately even on ontological questions. For our intuitive approach, we choose to go back to the origins of quantum field theory. In view of the many severe problems that had to be overcome on the way to modern quantum field ...
1. Jan. 2015 · This Element offers an introduction to selected philosophical issues that arise in contemporary particle physics, aimed at philosophers who have limited prior exposure to quantum field theory. One ...
27. Juli 2004 · Back to Top. Quantum Theory and Mathematical Rigor. First published Tue Jul 27, 2004; substantive revision Fri Mar 1, 2024. An ongoing debate in the foundations of quantum physics concerns the role of mathematical rigor. The contrasting views of von Neumann and Dirac provide interesting and informative insights concerning two sides of this debate.
