Physicists Achieve “Holy Grail” of Summing All Feynman Diagrams

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. Researchers at Caltech have developed a faster and more effective technique for calculating large sets of Feynman diagrams, which are visual tools used by physicists to describe how particles [...]
