Automatic Feynman diagram generation for nonlinear optical spectroscopies and application to fifth-order spectroscopy with pulse overlaps. [PDF]
Journal of Chemical Physics, 2020 Perturbative nonlinear optical spectroscopies are powerful methods to understand the dynamics of excitonic and other condensed phase systems. Feynman diagrams have long provided the essential tool to understand and interpret experimental spectra and to ...

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.

Multi-Loop Techniques for Massless Feynman Diagram Calculations [PDF]
Physics of particles and nuclei, 2018 We review several multi-loop techniques for analytical massless Feynman diagram calculations in relativistic quantum field theories: integration by parts, the method of uniqueness, functional equations and the Gegenbauer polynomial technique.

Feynman diagram description of 2D-Raman-THz spectroscopy applied to water. [PDF]
Journal of Chemical Physics, 2018 2D-Raman-THz spectroscopy of liquid water, which has been presented recently [J. Savolainen et al., Proc. Natl. Acad. Sci. U. S. A. 110, 20402 (2013)], directly probes the intermolecular degrees of freedom of the hydrogen-bond network.

New Results for a Two-Loop Massless Propagator-Type Feynman Diagram [PDF]
, 2016 We consider a two-loop massless propagator-type Feynman diagram with an arbitrary (noninteger) index on the central line. We analytically prove the equality of two well-known results in the literature expressing this diagram in terms of hypergeometric ...

Vacuum seagull: Evaluating a three-loop Feynman diagram with three mass scales [PDF]
, 2017 We study a 3-loop 5-propagator Feynman Integral, which we call the vacuum seagull, with arbitrary masses and spacetime dimension using the Symmetries of Feynman Integrals method. It is our first example with potential numerators.

Genus drop in hyperelliptic Feynman integrals [PDF]
Physical Review D, 2023 The maximal cut of the nonplanar crossed box diagram with all massive internal propagators was long ago shown to encode a hyperelliptic curve of genus 3 in momentum space. Surprisingly, in Baikov representation, the maximal cut of this diagram only gives

Twistor coverings and Feynman diagrams
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
