Quantum gravity tries to combine Einstein’s general theory of relativity with quantum mechanics. Quantum corrections to classical gravity are visualized as loop diagrams, as the one shown here ...

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 ...

How do you calculate infinite quantum outcomes? Feynman Diagrams. The equations of quantum field theory allow us to calculate the behaviour of subatomic particles by expressing them as vibrations ...

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?

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 ...

The revelation that particle interactions, the most basic events in nature, may be consequences of geometry significantly advances a decades-long effort to reformulate quantum field theory, the ...

Bianconi’s work extends this thermodynamic analogy, employing quantum relative entropy to bridge the gap between quantum field theory and general relativity.
