Deep Learning for Feynman's Path Integral in Strong-Field Time-Dependent Dynamics. [PDF]

open access: yesPhysical Review Letters, 2020
Feynman's path integral approach is to sum over all possible spatiotemporal paths to reproduce the quantum wave function and the corresponding time evolution, which has enormous potential to reveal quantum processes in the classical view.

Embedding Feynman integral (Calabi-Yau) geometries in weighted projective space [PDF]

open access: yesJournal of High Energy Physics, 2019
It has recently been demonstrated that Feynman integrals relevant to a wide range of perturbative quantum field theories involve periods of Calabi-Yau manifolds of arbitrarily large dimension.

Deriving canonical differential equations for Feynman integrals from a single uniform weight integral [PDF]

open access: yesJournal of High Energy Physics, 2020
Differential equations are a powerful tool for evaluating Feynman integrals. Their solution is straightforward if a transformation to a canonical form is found. In this paper, we present an algorithm for finding such a transformation.

Integral equation characterization of the Feynman–Kac formula for a regime-switching diffusion

open access: yesResults in Applied Mathematics, 2020
In this paper, we provide an integral equation characterization of the solution to a Cauchy problem associated to the Feynman–Kac formula for a regime-switching diffusion.

Feynman integral relations from parametric annihilators [PDF]

open access: yesLetters in Mathematical Physics, 2017
We study shift relations between Feynman integrals via the Mellin transform through parametric annihilation operators. These contain the momentum space integration by parts relations, which are well known in the physics literature.

Analytic Feynman Integral and a Change of Scale Formula for Wiener Integrals of an Unbounded Cylinder Function

open access: yesComplexity, 2020
We investigate the behavior of the unbounded cylinder function Fx=∫0Tα1tdxt2k⋅∫0Tα2tdxt2k⋅⋯⋅∫0Tαntdxt2k, k=1,2,… whose analytic Wiener integral and analytic Feynman integral exist, we prove some relationships among the analytic Wiener integral, the ...

Local mirror symmetry and the sunset Feynman integral [PDF]

open access: yes, 2016
We study the sunset Feynman integral defined as the scalar two-point self-energy at two-loop order in a two dimensional space-time. We firstly compute the Feynman integral, for arbitrary internal masses, in terms of the regulator of a class in the ...

A Feynman integral via higher normal functions [PDF]

open access: yesCompositio Mathematica, 2014
We study the Feynman integral for the three-banana graph defined as the scalar two-point self-energy at three-loop order. The Feynman integral is evaluated for all identical internal masses in two space-time dimensions. Two calculations are given for the

Internal reduction method for computing Feynman integrals

open access: yesJournal of High Energy Physics, 2020
A new approach to compute Feynman Integrals is presented. It relies on an integral representation of a given Feynman Integral in terms of simpler ones. Using this approach, we present, for the first time, results for a certain family of non-planar five ...

Feynman integral reduction using Gröbner bases

open access: yesJournal of High Energy Physics, 2023
We investigate the reduction of Feynman integrals to master integrals using Gröbner bases in a rational double-shift algebra Y in which the integration-by-parts (IBP) relations form a left ideal.
