Andreas Bartels, Objects or Events?: Towards an Ontology for Quantum Field Theory, Philosophy of Science, Vol. 66, Supplement. Proceedings of the 1998 Biennial Meetings of the Philosophy of Science ...

The quantum field theory framework needed some adjustment for Borinsky and Vogtmann to get the right count. For instance, in quantum field theory, two graphs that are mirror images of each other are ...

Visualization of a quantum field theory calculation showing virtual particles in the quantum vacuum. (Specifically, for the strong interactions.) Even in empty space, this vacuum energy is non-zero.

The AdS/CFT duality connects a theory of gravity in a space-time region called anti-de Sitter space (which curves differently than our universe) to an equivalent quantum field theory describing that ...

Quantum field theory marries the ideas of other quantum theories to depict all particles as “excitations” that arise in underlying fields. The British physicist Paul Dirac started the ball ...

Quantum mechanics is perhaps the most unintuitive theory ever devised. And yet it’s also the most successful, in terms of sheer predictive power. Simply by following the math of quantum ...

The same insights could have been found using quantum field theory, she said, but they weren’t. “It’s much more natural in string theory, with its extra structure.” ...

Quantum field theory is notoriously complicated, built from mind-bendingly abstract mathematics. But are the underlying rules of reality really so far from human intuition? Or are physicists just ...

“This work proposes that quantum gravity has an entropic origin and suggests that the G-field might be a candidate for dark matter,” Professor Bianconi told SciTechDaily in a statement.
