Using an advanced Monte Carlo method, Caltech researchers found a way to tame the infinite complexity of Feynman diagrams and ...

Learn about Richard Feynman, the Nobel Prize-winning physicist known for quantum electrodynamics, his unique teaching style, ...

A clever method from Caltech researchers now makes it possible to unravel complex electron-lattice interactions, potentially transforming how we understand and design quantum and electronic materials.

Through the work of Feynman, Dyson, Julian Schwinger and Sin-Itiro Tomonaga, a new and improved theory of quantum electrodynamics was born. Feynman’s lines and squiggles, which became known as Feynman ...

Caltech scientists have found a fast and efficient way to add up large numbers of Feynman diagrams, the simple drawings physicists use to represent particle interactions. The new method has already ...

The efforts of Dyson worked well, and the Feynman diagram spread, greatly affecting modern theoretical physics. However, as time goes on, it also turns out that Feinman diagrams have limitations.

When physicists model particle collisions they use a tool called a Feynman diagram, a simple schematic invented by Richard Feynman in the 1940s. To get a feel for these diagrams, consider a simple ...

Feynman diagrams have served physics well over the years, but they have limitations. One is strictly procedural. Physicists are pursuing increasingly high-energy particle collisions that require ...

Figure 4. You can export your Feynman diagram in several different formats. Since JaxoDraw is aimed at physicists, you'll most likely want to export your diagram into a form you easily can use with ...

I have always been surprised that Feynman diagrams were as usefull as they are. They seem so limited in what they can handle, but I guess for the "simple" problems needed to make nuclear ...
