All plus four point (A)dS graviton function using generalized on-shell recursion relation
Published 2023-05-01“…To achieve this, we employ a generalized recursion method that involves complexifying all external momentum of the graviton function, which results in the factorization of AdS graviton amplitudes and eliminates the need for Feynman-Witten diagrams. Our calculations were conducted in three boundary dimensions, with a particular emphasis on exploring cosmology and aiding the cosmological bootstrap program. …”

Integrability and holographic aspects of six-dimensional N = 1 , 0 $$ \mathcal{N}=\left(1,\ 0\right) $$ superconformal field theories
Published 2019-06-01“…Abstract In the framework of six-dimensional conformal field theories with N = 1 , 0 $$ \mathcal{N}=\left(1,\ 0\right) $$ supersymmetry we develop the map between the holographic description, the field theoretical description and the associated Hanany-Witten set-ups. General expressions that calculate various observables are presented. …”

Harmonic Spinors in the Ricci Flow
Published 2024“…It is shown that Perelman’s Ricci flow entropy can be expressed in terms of the energy of harmonic spinors in all dimensions, and in four dimensions, in terms of the energy of Seiberg–Witten monopoles. Consequently, Ricci flow is the gradient flow of these energies. …”

THE SU(3) TOPOLOGICAL SUSCEPTIBILITY AT ZERO AND FINITE TEMPERATURE - A LATTICE MONTE-CARLO EVALUATION
Published 1988“…This enables us to extract χt in physical units and we find χt=(179±4 MeV)4 - statistical error only - which is in striking agreement with the Witten-Veneziano calculation. We also investigate the previously observed fact that χt is suppressed as the temperature is raised through the deconfining transition. …”

Moduli stabilisation in heterotic string compactifications
Published 2006“…It is shown that these effective theories are consistent with four-dimensional N ≤ 1 supergravity and that the superpotential can be obtained by a Gukov-Vafa-Witten type formula. Within these generalized models, we find consistent supersymmetric (AdS) vacua at weak gauge coupling, provided we allow for general internal gauge bundles. …”
