Advances in Position‐Momentum Entanglement: A Versatile Tool for Quantum Technologies

open access: yesLaser &Photonics Reviews, Volume 20, Issue 15, 7 August 2026.
Position–momentum entanglement constitutes a high‐dimensional continuous‐variable resource in quantum optics. Recent advances in its generation, characterization, and control are reviewed, with emphasis on spontaneous parametric down‐conversion and modern measurement techniques.

Teleseismic S‐Wave Coda Autocorrelation and vp/vs ${v}_{p}/{v}_{s}$ Distribution Over the Antarctic Ice Sheet

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Accurate characterization of the compressional to shear (P‐to‐S) wave‐speed ratio (vp/vs ${v}_{p}/{v}_{s}$) within the Antarctic Ice Sheet (AIS) is crucial for understanding its internal structure, mechanical stability, and vulnerability to a changing climate.

Surrogate‐Assisted Bayesian Inference of Fracture Network Parameters From Elastic Waves: A Sensitivity‐Guided Approach

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract We develop a sensitivity‐guided, surrogate‐assisted Bayesian framework to infer fracture network parameters from elastic waves. Synthetic fracture networks characterized by power‐law length exponent a $a$, fracture density d $d$, and percolation parameter p $p$ are constructed.

Localization and Classification of Gravity Wave Events From VIIRS Day/Night Band Satellite Imagery Using Machine Learning Techniques

open access: yesEarth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Gravity waves in the upper mesosphere produce diverse spatial patterns in nighttime airglow, but their global morphology has been difficult to characterize because manual identification is impractical for the massive satellite image archive. We developed a machine learning framework to detect and classify gravity wave events in imagery from ...

Convergent‐beam X‐ray crystallography

open access: yesJournal of Applied Crystallography, Volume 59, Issue 4, Page 1200-1218, August 2026.
Molecular crystal diffraction with a highly focused X‐ray beam decouples crystal morphology and molecular structure by measuring magnified topographs from every reflection.Molecular and polymeric crystals show a wide range of functional properties that arise from the interplay between the atomic‐scale structure of their constituent molecules and the ...
