Thermal Conduction in Laser‐Driven Tin Plasmas and the Sensitivity of Plasma Properties to the Flux Limiter

Contributions to Plasma Physics, EarlyView.
ABSTRACT We study the role of thermal conduction in laser‐produced tin plasma sources of extreme ultraviolet (EUV) light using radiation‐hydrodynamic simulations. Adopting the flux‐limited Spitzer–Härm approach, we investigate the sensitivity of the electron temperature, electron density, net in‐band emissivity, and conversion efficiency to the choice ...

Reconstruction of Solar Extreme-ultraviolet Irradiance Using Ca II K Images and SOHO/SEM Data with Bayesian Deep Learning and Uncertainty Quantification

The Astrophysical Journal Supplement Series
Solar extreme-ultraviolet (EUV) irradiance plays a crucial role in heating the Earth’s ionosphere, thermosphere, and mesosphere, affecting atmospheric dynamics over varying time scales.

Monolithically integrated vanadium oxide photodetection breaking spectral limitations

InfoScience, EarlyView.
We demonstrate monolithically integrated ultra‐broadband vanadium oxide photodetection from the visible to the mid‐infrared spectrum by leveraging the optical–thermal–resistance effect. With a micrometer‐scale footprint, the integrated photodetector delivers a fast response time of ∼26.24 μs.

Reconfigurable Geometric Phase Matching by Multilayered Nonlinear Thin‐Film Crystals

Laser &Photonics Reviews, EarlyView.
The concept of geometric phase matching is demonstrated as a dynamically reconfigurable approach for tunable nonlinear wave mixing in multilayered nonlinear thin‐film crystals. Experimental results reveal full modulation in a bilayer structure and near‐perfect spin‐selective phase matching of second‐harmonic generation in an eight‐layer configuration ...

HelioFill: History-conditioned Diffusion Estimation of Solar Far-side EUV Emission

The Astrophysical Journal Letters
The loss of STEREO-B in 2014 created a persistent blind spot in extreme ultraviolet (EUV) imaging of the solar far-side. We present HelioFill, which is, to the authors’ knowledge, the first denoising-diffusion inpainting model that estimates the ...

Methods for substituting onsite ambient ultraviolet radiation measurements for personal exposure studies

Photochemistry and Photobiology, EarlyView.
Three methods for substituting on‐site ambient ultraviolet radiation measurements for personal exposure measurements were investigated. Assuming spatial persistency of measurements from high‐grade instruments delivers lowest uncertainties up to distances of 82 km.

Spatial Distribution of Return Flows Occurrence in the Venusian Magnetotail and Its Dependence on Upstream Conditions

Geophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract Venus‐ward return flow can significantly influence ion escape from Venus and may therefore play an important role in atmospheric evolution. However, the mechanism driving return flow remains under debate. Here, we investigate the occurrence rate and spatial distribution of ion return flows in the Venusian induced magnetotail, and their ...

Multidomain Solar Extreme-ultraviolet Image Translation and Its Application to Differential Emission Measure Analysis

The Astrophysical Journal Supplement Series
We develop five multidomain models for solar extreme-ultraviolet (EUV) image translation, investigate their dependence on input data and solar cycle phase, and apply them to differential emission measure (DEM) analysis.

Self‐Assembly of a Colloidal Honeycomb Crystal in Silico for Topological Valley Photonics

Small, Volume 22, Issue 62, 6 November 2026.
The self‐assembly of a colloidal honeycomb crystal is demonstrated in computer simulations, using an assembly strategy that not only suppresses the formation of real‐space topological defects observed experimentally but also yields topological photonic properties in reciprocal space.
