Radiation eikonal for post-Minkowskian observables [PDF]
A recent proposal reinterprets the eikonal as the scattering generator, whichcomputes scattering observables through an action as a symmetry generator.

Worldline formalism, eikonal expansion and the classical limit of scattering amplitudes
Nuclear Physics BWe revisit the fundamentals of two different methods for calculating classical observables: the eikonal method, which is a scattering amplitude-based method, and the worldline quantum field theory (WQFT) method.

Subleading eikonal, AdS/CFT and double stress tensors
Journal of High Energy Physics, 2019 The eikonal phase which determines the Regge limit of the gravitational scat- tering amplitude of a light particle off a heavy one in Minkowski spacetimes admits an expansion in the ratio of the Schwarzschild radius of the heavy particle to the impact ...

Seismic imaging of the critical zone of dolerite dykes at Cap Fréhel in Brittany (France)
Near Surface Geophysics, Volume 24, Issue 3, Page 262-288, June 2026.Abstract In June 2023, we measured ten near‐surface seismic profiles to image the critical zone of dolerite (diabase) dykes that cut the sandstone at Cap Fréhel in Brittany (France). Seismic ray tracing and inversion are used to determine the thickness of the regolith layer from first‐arrival P‐wave traveltimes.

Potential scattering in the eikonal approximation
, 1971 The eikonal wave function and scattering amplitude for potential scattering are obtained by using elliptic confocal coordinates to evaluate the total Green's function in the short wave length limit.

Ringdown Modulation of Acceleration Radiation in the Schwarzschild Background
Fortschritte der Physik, Volume 74, Issue 6, June 2026.ABSTRACT We derive an analytic first‐order description of how Schwarzschild ringdown affects a detector‐based detailed‐balance diagnostic in a near‐horizon, single‐mode setting. A freely falling two‐level system couples to a cavity‐filtered outgoing mode of fixed asymptotic frequency, whose static Schwarzschild response gives geometric photon ...

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.Abstract In situ CO2 mineral storage is gaining increasing attention as a carbon capture and storage (CCS) technology to reduce anthropogenic CO2 emissions. So far, in situ CO2 mineral storage projects have been monitored predominantly using fluid‐ and isotope geochemical methods.

Sulla Regolarità delle soluzioni di viscosità dell'equazione iconale
Bruno Pini Mathematical Analysis Seminar, 2010 We study the regularity of a viscosity solution of equations of eikonal type in two dierent framework: we consider either the non-degenerate eikonal equation under low regularity assumptions on the data or a possibly degenerate eikonal equation with data
