They are famous for intuitively assembling all possible histories for a given scattering process such that amplitudes can be obtained from associating mathematical quantities to the diagrams. Web$\begingroup$ String theory is formulated using Feynman's sum over history formalism. The basic equation is just the path integral. The basic equation is just the path integral. The thing that makes strings difficult, in some sense, is that we don't understand very well what variables we should be using in this path integral. $\endgroup$ harvardprotect.com

WebApr 12, 2024 · One common approach which generalizes more nicely to relativistic quantum field theory is Feynman's path integral formalism. This approach uses a generalization of Lagrangian mechanics where the relevant Lagrangian is integrated over all possible paths between two classical endpoints, so it is sometimes called the sum-over-paths formalism. In the 20th century, two theoretical frameworks emerged for formulating the laws of physics. The first is Albert Einstein's general theory of relativity, a theory that explains the force of gravity and the structure of spacetime at the macro-level. The other is quantum mechanics, a completely different formulation, which uses known probability principles to describe physical phenomena at the micro-level…

WebJan 2, 2024 · In the Feynman perturbation series.

WebIn mathematical physics, Yang–Mills theory is a gauge theory based on a special unitary group SU(N), or more generally any compact, reductive Lie algebra.Yang–Mills theory seeks to describe the behavior of elementary particles using these non-abelian Lie groups and is at the core of the unification of the electromagnetic force and weak forces (i.e. …

WebApr 11, 2024 · String field theory (SFT) is a formulation of string theory that reframes the dynamics of relativistic strings in terms of a quantum field theory.
