Scattering amplitude annihilators [PDF]
Journal of High Energy Physics, 2020 Several second order differential operators are shown to annihilate the YM and GR tree scattering amplitudes. In particular we prove a conjecture of Loebbert, Mojaza and Plefka from their investigation of a hidden conformal symmetry in GR.Comment: 31 ...

Quantum Amplitude Amplification and Estimation [PDF]
, 2000 Consider a Boolean function $\chi: X \to \{0,1\}$ that partitions set $X$ between its good and bad elements, where $x$ is good if $\chi(x)=1$ and bad otherwise. Consider also a quantum algorithm $\mathcal A$ such that $A |0\rangle= \sum_{x\in X} \alpha_x

Expansion of Einstein-Yang-Mills Amplitude [PDF]
, 2017 In this paper, we provide a thorough study on the expansion of single trace Einstein-Yang-Mills amplitudes into linear combination of color-ordered Yang-Mills amplitudes, from various different perspectives.

Spinning amplitudes from scalar amplitudes [PDF]
Journal of High Energy Physics, 2021 AbstractWe provide a systematic method to compute tree-level scattering amplitudes with spinning external states from amplitudes with scalar external states in arbitrary spacetime dimensions. We write down analytic answers for various scattering amplitudes, including the four graviton amplitude due to the massive spinJexchange. We verify the results by

Near-single-cycle pulses generated through post-compression on FAB1 laser at ATTOLAB-Orme facility [PDF]
EPJ Web of Conferences, 2021 Generating high-energy few-cycle pulses is key in the study of light-matter interaction in the regime of high field physics. Attosecond science possess the necessary time resolution to study the underlying fundamental processes but requires repetitions ...

Waveforms from amplitudes [PDF]
Physical Review D, 2022 We show how to compute classical wave observables using quantum scattering amplitudes. We discuss observables both with incoming and with outgoing waves. The required classical limits are naturally described by coherent states of massless bosons.

Advances in Femtosecond Laser GHz-Burst Drilling of Glasses: Influence of Burst Shape and Duration
Micromachines, 2023 The femtosecond GHz-burst mode laser processing has attracted much attention in the last few years. Very recently, the first percussion drilling results obtained in glasses using this new regime were reported. In this study, we present our latest results

Journal of High Energy Physics, 2012 Abstract Tree-level amplitudes of gauge theories are expressed in a basis of auxiliary amplitudes with only cubic vertices. The vertices in this formalism are explicitly factorized in color and kinematics, clarifying the color-kinematics duality in gauge theory amplitudes.
