Hunga‐Tonga Volcano Plumbing System Inferred From Virtual Seismometer Approach

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract We present a surface wave tomography application based on event‐pair interferometry to investigate local (∼100 km) mid‐ocean crustal structures, with a particular focus on imaging a potential crustal solidified intrusive complex in a region lacking seismic stations.

Worldline formalism, eikonal expansion and the classical limit of scattering amplitudes

Nuclear Physics B
We 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 ...

Hopf maps as static solutions of the complex eikonal equation

, 2004
We demonstrate that a class of torus-shaped Hopf maps with arbitrary linking number obeys the static complex eikonal equation. Further, we explore the geometric structure behind these solutions, explaining thereby the reason for their existence.

Seismicity, Repeating Earthquakes, and Tomographic Imaging of the Blanco Transform Fault System, Northeast Pacific

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract The Blanco transform fault system (BTFS) represents an evolving transform plate boundary in the Northeast Pacific Ocean. Its seismic behavior was captured with a dense network of 54 ocean‐bottom seismometers (OBS) operated for 1 year. We created a high‐resolution earthquake catalog based on different machine‐learning onset pickers.

The eikonal model of reactions involving exotic nuclei; Roy Glauber's legacy in today's nuclear physics

SciPost Physics Proceedings, 2020
In this contribution, the eikonal approximation developed by Roy Glauber to describe high-energy quantum collisions is presented. This approximation has been-and still is-extensively used to analyse reaction measurements performed to study the ...

A New Glauber Theory based on Multiple Scattering Theory

, 2008
Glauber theory for nucleus-nucleus scattering at high incident energies is reformulated so as to become applicable also for the scattering at intermediate energies. We test validity of the eikonal and adiabatic approximations used in the formulation, and

Layered Seismic Anisotropy and Tectonics of the Anatolian Plate

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Anatolian tectonics are associated with slab retreat in the west and gravitational potential energy and continental collision in the east, leading to westward motion of Anatolia relative to Eurasia, partially accommodated on the North and East Anatolian transform faults.

Final state interactions and the transverse structure of the pion using non-perturbative eikonal methods

, 2009
In the factorized picture of semi-inclusive hadronic processes the naive time reversal-odd parton distributions exist by virtue of the gauge link which renders it color gauge invariant.

Impact of Non‐Classical Gravity‐Wave Dynamics on Middle‐Atmosphere Mean Flow and Solar Tides

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 8, 28 April 2026.
Abstract Conventional gravity‐wave (GW) parameterizations neglect three aspects of GW dynamics. Instead of momentum and entropy fluxes they use Eliassen‐Palm fluxes, thereby neglecting the possibility that resolved flow are not in geostrophic and hydrostatic balance.
