Assessing Co‐Located NISAR and Sentinel‐1 Observations for Atmospheric Characterization
Journal of Geophysical Research: Atmospheres, Volume 131, Issue 19, 16 October 2026.Abstract Tropospheric delay remains one of the largest sources of uncertainty in repeat‐pass Interferometric Synthetic Aperture Radar (InSAR) measurements, while accurate three‐dimensional deformation retrieval continues to be limited by the geometry of current spaceborne SAR systems.

Nanophotonics, Volume 15, Issue 19, 13 October 2026.Skyrmion topology is shown to emerge spontaneously in scalar fields of driven‐dissipative optical microcavities, without externally imposed phase structure. In exciton‐polariton condensates, non‐Hermitian flow generates isolated Skyrmions and self‐organized Skyrmion lattices, while optical nonlinearities enable switching and reconfiguration of their ...

Advanced Engineering Materials, Volume 28, Issue 19, 7 October 2026.Deep‐UV (258 nm) femtosecond pulses enable uniform amorphous silicon writing on Si(100)/(111) with a six‐fold larger fluence amorphization window than NIR methods. Optimized fluence and overlap yield 20–45 nm uniform and continuous amorphous layers. Microscopy shows sharp interfaces, and real‐time reflectivity reveals nanosecond melt–resolidification ...

Glissile Interphase Boundaries Enable Collective Phase Switching in Epitaxial Polar Oxides
Advanced Functional Materials, Volume 36, Issue 81, 8 October 2026.A triple point is identified in the phase diagram of low‐symmetry epitaxial BiFeO3 thin film along with an extended regime of phase competition associated with a flattened energy landscape. The electromechanical response is shown to be governed by correlated interphase‐boundary motion, including scale‐free avalanche dynamics characteristic of systems ...

In Situ Two‐Dimensional Residual Stress Characterization of Thin Films
Advanced Materials Technologies, Volume 11, Issue 19, 7 October 2026.An integrated in situ curvature metrology platform combining speckle‐based curvature optical metrology (SCOM) with multi‐beam optical sensors (MOS) enables spatially resolved two‐dimensional curvature mapping of thick sputtered coatings. The SCOM technique provides excellent agreement with MOS while providing an extended measurable curvature range ...

Beating the Standard Quantum Limit With Single‐Photon‐Added Coherent States
Advanced Physics Research, Volume 5, Issue 10, October 2026.The standard quantum limit (SQL) defines how quantum fluctuations of light constrain measurement precision. Here, we show that injecting a single‐photon‐added coherent state and a weak coherent state in the input ports of a Mach–Zehnder interferometer reduces phase uncertainty below the SQL.
