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 ...

Loop quantum gravity, by contrast, is concerned less with the matter that inhabits space-time than with the quantum properties of space-time itself. In loop quantum gravity, or LQG, space-time is a ...

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 ...

When it comes to the question of a quantum theory of gravity, it's often said that string theory is the only game in town. These four alternatives might cause a rethink of that.

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

Quantum mechanics is the study of atomic and subatomic particles at normal speeds, while quantum field theory is the study of those same particles at relativistic speeds.
