Integrated correlators in N $$ \mathcal{N} $$ = 4 super Yang-Mills and periods
Journal of High Energy Physics, 2022 We study perturbative aspects of recently proposed integrated four-point correlators in N $$ \mathcal{N} $$ = 4 supersymmetric Yang-Mills with all classical gauge groups using standard Feynman diagram computations.

physica status solidi (b), EarlyView.The response of graphene and MoS2 monolayers to highly‐charged impinging ions is investigated using nonequilibrium Green functions theory. Electronic correlations are found to have a significantly stronger influence on the ultrafast ion‐induced electron dynamics in MoS2 than in graphene.

Labelled tree graphs, Feynman diagrams and disk integrals
Journal of High Energy Physics, 2017 In this note, we introduce and study a new class of “half integrands” in Cachazo-He-Yuan (CHY) formula, which naturally generalize the so-called Parke-Taylor factors; these are dubbed Cayley functions as each of them corresponds to a labelled tree graph.

Tunnelling amplitudes through localised external potentials from Feynman diagram summation
European Physical Journal C: Particles and FieldsCurrently there is no general theory of quantum tunnelling of a particle through a potential barrier which is compatible with QFT. We present a complete calculation of tunnelling amplitudes for a scalar field for some simple potentials using quantum ...

Measure‐valued processes for energy markets
Mathematical Finance, Volume 35, Issue 2, Page 520-566, April 2025.Abstract We introduce a framework that allows to employ (non‐negative) measure‐valued processes for energy market modeling, in particular for electricity and gas futures. Interpreting the process' spatial structure as time to maturity, we show how the Heath–Jarrow–Morton approach can be translated to this framework, thus guaranteeing arbitrage free ...

Integrable Feynman graphs and Yangian symmetry on the loom
Journal of High Energy PhysicsWe present significant evidence that the powerful property of Yangian invariance extends to a new large class of conformally invariant Feynman integrals. Our results apply to planar Feynman diagrams in any spacetime dimension dual to an arbitrary network
