Spinning black hole binary dynamics, scattering amplitudes, and effective field theory [PDF]
Physical Review D, 2020 We describe a systematic framework for finding the conservative potential of compact binary systems with spin based on scattering amplitudes of particles of arbitrary spin and effective field theory.

Rigorous analysis of extremely asymmetrical scattering of electromagnetic waves in slanted periodic gratings [PDF]
, 2001 Extremely asymmetrical scattering (EAS) is a new type of Bragg scattering in thick, slanted, periodic gratings. It is realised when the scattered wave propagates parallel to the front boundary of the grating.

Transient chaos analysis of string scattering
Journal of High Energy Physics, 2022 It has long been thought that a highly excited string can be regarded as a black hole: the correspondence principle between strings and a black hole, while recent studies found that black holes are characterized by chaos.

Scattering amplitude from Bethe-Salpeter wave function inside the interaction range [PDF]
, 2018 We propose a method to calculate scattering amplitudes using the Bethe-Salpeter wave function inside the interaction range on the lattice. For an exploratory study of this method, we evaluate a scattering length of $I=2$ S-wave two pions by the use of ...

Measuring the phase of the scattering amplitude with vortex beams [PDF]
, 2012 We show that colliding vortex beams instead of (approximate) plane waves can lead to a direct measurement of how the overall phase of the plane wave scattering amplitude changes with the scattering angle. Since vortex beams are coherent superpositions of

Volume oscillation and acoustical scattering of a gas bubble [PDF]
MATEC Web of Conferences, 2019 The exact solution of a gas bubble’ volume was obtained based on volume oscillation of a gas bubble. The volume pulsation, acoustic impedance, scattering pressure of a gas bubble, acoustical power of scattering and acoustical scattering cross section of ...

Scattering amplitudes from dispersive iterations of unitarity
Journal of High Energy Physics, 2023 We present and numerically implement a computational method to construct relativistic scattering amplitudes that obey analyticity, crossing, elastic and inelastic unitarity in three and four spacetime dimensions.

Direct proof of the tree-level scattering amplitude recursion relation in Yang-mills theory. [PDF]
Physical Review Letters, 2005 Recently, by using the known structure of one-loop scattering amplitudes for gluons in Yang-Mills theory, a recursion relation for tree-level scattering amplitudes has been deduced.
