Optical Skyrmions with Tunable or Reconfigurable Topology Using Spin‐Decoupled Metaoptics

Laser &Photonics Reviews, Volume 20, Issue 14, 22 July 2026.
The work introduces advanced optical elements capable of generating and dynamically reconfiguring complex light patterns known as optical skyrmions. By precisely shaping light polarization at the nanoscale, a single engineered metasurface can generate and manipulate robust and tunable polarization textures in an efficient and scalable way.

An Information Geometry‐Based Method to Study Atmospheric and Seismic Phenomena With VLF Signals

Earth and Space Science, Volume 13, Issue 7, July 2026.
Abstract We propose to employ the framework of information geometry to detect anomalies in Very Low Frequency (VLF) and Low Frequency (LF) signal propagation, measured globally across amplitude and phase channels. Using a sliding‐window approach, the probability distributions of signal data are compared over adjacent intervals, defining a statistical ...

Impact of Magnetosphere Forcing and Model Resolution on Joule Heating Estimates in WACCM‐X During the 24 August 2005 Storm

Earth and Space Science, Volume 13, Issue 7, July 2026.
Abstract We investigate the high‐latitude Joule heating in a recently developed high‐resolution configuration of the WACCM‐X whole‐atmosphere model coupled to the MAGE model. Model resolution and geomagnetic forcing effects during the severe (Kp>8) $(Kp > 8)$ geomagnetic storm on 24 August 2005 are analyzed, distinguishing storm peak and recovery ...

Forward Image Registration for Higher Level Interpretation of Zircon Provenance Based on Combined CL, U/Pb Age, and Geochemical Data

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Most detrital zircon studies generate grayscale cathodoluminescence (CL) images, U/Pb dates, and variably extensive trace element concentration data. Yet the combined information contained in these data is rarely used for a higher‐level interpretation of zircon provenance, which still heavily relies on comparison of sample‐wide U/Pb age ...

A Self-consistent Model of Shock-heated Plasma in Nonequilibrium States for Direct Parameter Constraints from X-Ray Observations

The Astrophysical Journal
X-ray observations of shock-heated plasmas, such as those found in supernova remnants (SNRs), often exhibit features of temperature and ionization nonequilibrium. For accurate interpretation of these observations, proper calculations of the equilibration

Linking the Tectonic Evolution of Hainan Island and Borneo Since the Paleozoic: Implication for Interaction Between the Tethyan and Paleo‐Pacific Tectonic Domains in Southeast Asia

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract The interaction between the Tethyan and Paleo‐Pacific subduction systems in Southeast Asia since the Paleozoic is still poorly understood. Hainan Island and Borneo, located near the junction of the Tethyan and Paleo‐Pacific domains, provide the critical regions for understanding the dynamic processes and interaction between the two tectonic ...

Magma Mixing Processes in a Continental Collision Zone: Insights From Mineralogical and Geochemical Constraints

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Eocene magmatism in southern Tibet records deep geodynamic processes associated with the India‐Asia collision. The Quxu batholith, a representative segment of the Gangdese magmatic belt, hosts widespread mafic microgranular enclaves (MMEs) indicating magma mixing.

The Magnetic Mineralogy of Carbonaceous Chondrites: A Microscopy and Machine Learning Study of Meteorite WIS 91600

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract A central challenge in the paleomagnetic study of meteorites is to characterize their diverse remanence carriers. Here, we develop a machine‐learning assisted workflow that combines multi‐scale (mm to nm) and multi‐dimensional (2D‐3D) microscopy to build a comprehensive picture of ferromagnetic mineralogy in the C2 ungrouped carbonaceous ...

Frozen-field Modeling of Coronal Condensations with MPI-AMRVAC. I. Demonstration in Two-dimensional Models

The Astrophysical Journal
Large-scale coronal plasma evolutions can be adequately described by magnetohydrodynamics (MHD) equations. However, full multidimensional MHD simulations require substantial computational resources.

Deterministic Propagation of Suprathermal Ions Through the Heliosphere

Journal of Geophysical Research: Space Physics, Volume 131, Issue 7, July 2026.
Abstract The PEPSSI instrument onboard New Horizons is sampling the energy range that bridges pickup and suprathermal He+ ${\mathrm{H}\mathrm{e}}^{+}$ ions for the first time in the outer heliosphere. New Horizons repeatedly encountered structures beyond 30 au that we interpret as the spiral of a corotating interaction region (CIR) for an extended ...
