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.

Group invariants for Feynman diagrams [PDF]
SciPost Physics Proceedings, 2023 It is well-known that the symmetry group of a Feynman diagram can give important information on possible strategies for its evaluation, and the mathematical objects that will be involved. Motivated by ongoing work on multi-loop multi-photon amplitudes in

Feynman diagrams and $Ω$-deformed M-theory [PDF]
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.

Gravitational lensing of the CMB: A Feynman diagram approach
Physics Letters B, 2014 We develop a Feynman diagram approach to calculating correlations of the Cosmic Microwave Background (CMB) in the presence of distortions. As one application, we focus on CMB distortions due to gravitational lensing by Large Scale Structure (LSS).

Parallel Computation of Feynman diagrams with DIANA [PDF]
, 2003 Co-operation of the Feynman DIagram ANAlyzer (DIANA) with the underlying operational system (UNIX) is presented. We discuss operators to run external commands and a recent development of parallel processing facilities and an extension in the spirit of a ...

The diagrammatic coaction and cuts of the double box
SciPost Physics Proceedings, 2022 The diagrammatic coaction encodes the analytic structure of Feynman integrals by mapping any given Feynman diagram into a tensor product of diagrams defined by contractions and cuts of the original diagram.

Feynman rules for scalar conformal blocks
Journal of High Energy Physics, 2022 We complete the proof of “Feynman rules” for constructing M-point conformal blocks with external and internal scalars in any topology for arbitrary M in any spacetime dimension by combining the rules for the blocks (based on their Witten diagram ...
