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 ...

The resulting theoretical developments brought about modern quantum field theory, and the interactions with virtual particles — the modern way to quantify the effects of “the radiation field ...

A diagram of the double-slit experiment according to pilot-wave theory. ... while quantum field theory is the study of those same particles at relativistic speeds.

So, yeah, quantum field theory is a type of madness. An again, we've been down that rabbit hole. In particular, we've looked a bit at Feynman diagrams, which are our best tool for dealing with the ...

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 ...
