A supersymmetric exotic field theory in (1+1) dimensions: one loop soliton quantum mass corrections

open access: yesJournal of High Energy Physics, 2018
We consider one loop quantum corrections to soliton mass for the N = 1 $$ \mathcal{N}=1 $$ supersymmetric extension of the (1+1)-dimensional scalar field theory with the potential U (ϕ) = ϕ 2 cos2 (ln ϕ 2).

A Graph-Based Power Flow Method for Balanced Distribution Systems

open access: yesEnergies, 2018
A power flow method based on graph theory is presented for three-phase balanced distribution systems. The graph theory is used to describe the power network and facilitate the derivation of the relationship between bus Currents and the bus Voltage Bias ...

Integrating three-loop modular graph functions and transcendentality of string amplitudes [PDF]

open access: yesJournal of High Energy Physics, 2021
Modular graph functions (MGFs) are SL(2, ℤ)-invariant functions on the Poincaré upper half-plane associated with Feynman graphs of a conformal scalar field on a torus.

Motivic Geometry of two-Loop Feynman Integrals [PDF]

open access: yesQuarterly Journal of Mathematics, 2023
We study the geometry and Hodge theory of the cubic hypersurfaces attached to two-loop Feynman integrals for generic physical parameters. We show that the Hodge structure attached to planar two-loop Feynman graphs decomposes into mixed Tate pieces and ...

Feynman integrals for binary systems of black holes

open access: yesSciPost Physics Proceedings, 2022
The initial phase of the inspiral process of a binary black-hole system can be described by perturbation theory. At the third post-Minkowskian order a two-loop double box graph, known as H-graph, contributes.

The H-graph with equal masses in terms of multiple polylogarithms

open access: yesPhysics Letters B, 2021
The initial phase of the inspiral process of a binary system producing gravitational waves can be described by perturbation theory. At the third post-Minkowskian order a two-loop double box graph, known as H-graph contributes.
