On perturbative scattering amplitudes in maximally supersymmetric theories
, 2011 PhDThere has been substantial calculational progress in the last few years in maximally supersymmetric theories, revealing unexpected simplicity, new structures and symmetries. In this thesis, after reviewing some of the recent advances in N = 4 super

Holographic corrections to meson scattering amplitudes
Nuclear Physics B, 2017 We compute meson scattering amplitudes using the holographic duality between confining gauge theories and string theory, in order to consider holographic corrections to the Veneziano amplitude and associated higher-point functions.

Supertranslations from Scattering Amplitudes
Physical Review LettersOn shell methods have found a new application to local observables such as asymptotic radiation fields and gravitational waveforms. While these observables are invariant under small gauge transformations, they are known to depend on a choice of asymptotic gauge; in gravity on asymptotically Minkowski spacetimes, this is a choice of Bondi-Van der Burg ...

Machine Learning‐Assisted Inverse Design of Soft and Multifunctional Hybrid Liquid Metal Composites
Advanced Functional Materials, EarlyView.A machine learning framework is presented for inverse design of synthesizable multifunctional composites containing both liquid metal and solid inclusions. By integrating physics‐based modeling, data‐driven prediction, and Bayesian optimization, the approach enables intelligent design of experiments to identify optimal compositions and realize these ...

Novel approaches to perturbative scattering amplitudes in gauge theory and gravity
, 2009 PhDScattering amplitudes of massless quanta play a crucial role in the calculation of cross sections for multi-jet production at hadron colliders. The framework provided by perturbative quantum field theory, based on Feynman diagrams, does not capture ...

Aspects of scattering amplitudes: on strong backgrounds and in twistor space [PDF]
In this thesis we study the properties of scattering amplitudes in two contexts: in the presence of strong background fields; and their twistorial representations.

Advanced Functional Materials, EarlyView.This work introduces a swelling‐induced, stress‐assisted water‐soluble PVA tape strategy to transfer‐print nanodiamond quantum‐sensor arrays onto soft, curved biological interfaces. The room‐temperature, water‐triggered process achieves >98% fidelity and residue‐free integration, enabling conformal quantum sensing on contact lenses, neural probes, and ...

Serendipitous syzygies of scattering amplitudes
Physical Review DWe study linear relations between color-ordered all-plus amplitudes at one loop in Yang-Mills theory. We show that on general grounds, there are ( n − 1 ) ! /

Y‐system for scattering amplitudes [PDF]
Fortschritte der Physik, 2011 AbstractWe review recent progress on computing scattering amplitudes of planar 𝒩 = 4 super Yang‐Mills at strong coupling by using the AdS/CFT duality. The problem boils down to the computation of certain minimal areas on AdS. We show how to use the integrability of the classical equations of motion in order to efficiently compute such minimal areas.
