Combinatorial summation of Feynman diagrams [PDF]
Nature Communications, 2023 Feynman’s diagrammatic series is a common language for a formally exact theoretical description of systems of infinitely-many interacting quantum particles, as well as a foundation for precision computational techniques.

Generalized planar Feynman diagrams: collections [PDF]
Journal of High Energy Physics, 2020 Tree-level Feynman diagrams in a cubic scalar theory can be given a metric such that each edge has a length. The space of metric trees is made out of orthants joined where a tree degenerates.

Feynman diagrams and rooted maps [PDF]
Open Physics, 2018 The rooted maps theory, a branch of the theory of homology, is shown to be a powerful tool for investigating the topological properties of Feynman diagrams, related to the single particle propagator in the quantum many-body systems.

Scattering Equations and Feynman Diagrams [PDF]
Journal of High Energy Physics, 2015 We show a direct matching between individual Feynman diagrams and integration measures in the scattering equation formalism of Cachazo, He and Yuan. The connection is most easily explained in terms of triangular graphs associated with planar Feynman ...

Twistor coverings and Feynman diagrams [PDF]
Journal of High Energy Physics, 2022 Recently, a worldsheet dual to free N $$ \mathcal{N} $$ = 4 Super Yang-Mills has been proposed in terms of twistor variables for AdS5, in parallel to that for the AdS3 dual to the free symmetric orbifold CFT. In the latter case, holomorphic covering maps

Ladder and zig-zag Feynman diagrams, operator formalism and conformal triangles [PDF]
Journal of High Energy Physics, 2023 We develop an operator approach to the evaluation of multiple integrals for multiloop Feynman massless diagrams. A commutative family of graph building operators H α for ladder diagrams is constructed and investigated.

Learning Feynman Diagrams with Tensor Trains [PDF]
Physical Review X, 2022 We use tensor network techniques to obtain high-order perturbative diagrammatic expansions for the quantum many-body problem at very high precision. The approach is based on a tensor train parsimonious representation of the sum of all Feynman diagrams ...

Position space equations for banana Feynman diagrams [PDF]
Nuclear Physics B, 2023 The answers for Feynman diagrams satisfy various kinds of differential equations – which is not a surprise, because they are defined as Gaussian correlators, possessing a vast variety of Ward identities and superintegrability properties.

Feynman diagrams and $Ω$-deformed M-theory
SciPost Physics, 2021 We derive the simplest commutation relations of operator algebras associated to M2 branes and an M5 brane in the $\Omega$-deformed M-theory, which is a natural set-up for Twisted holography.
