Feynman Diagrams. The equations of quantum field theory allow us to calculate the behaviour of subatomic particles by expressing them as vibrations in quantum fields.

Feynman diagrams are incredibly useful, but they're a perturbative (i.e., approximate) approach to calculating, and quantum field theory often yields fascinating, unique results when you take a ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

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 ...

We all love Richard Feynman, but his diagrams may have to go. We all love Richard Feynman, ... Arkani-Hamed and Trnka hope to gain a deeper understanding of the nature of quantum field theory.

Landauer's principle is a thermodynamics concept also relevant in information theory, which states that erasing one bit of ...

Quantum mechanics isn’t sufficient to explain the Universe; for that, quantum field theory is needed. This is why. Schematic animation of a continuous beam of light being dispersed by a prism.

A unified theory of everything has long eluded scientists due to gravity being irreconcilable with the three other fundamental forces (electromagnetic, weak, and strong) described using quantum ...

Quantum Entanglement is the biggest mystery of science that could upend life as we know it, and explaining it is an unlikely but fascinating theory writes Satyen K. Bordoloi. It is the stuff of ...
