Mid‐Infrared Integrated Photonics: Material Platforms and Emerging Applications

Laser &Photonics Reviews, Volume 20, Issue 6, 18 March 2026.
Mid‐infrared (MIR) integrated photonics enables advanced chemical and biological sensing through the unique absorption features of molecules in the 2–20 µm range. This review highlights recent material advances such as chalcogenide glasses, silicon, and graphene and explores MIR applications in environmental monitoring, medical diagnostics ...

Monopoles, Clarified

Fortschritte der Physik, Volume 74, Issue 3, March 2026.
ABSTRACT We propose a manifestly duality‐invariant, Lorentz‐invariant, and local action to describe quantum electrodynamics in the presence of magnetic monopoles that derives from Sen's formalism. By employing field strengths as the dynamical variables, rather than potentials, this formalism resolves longstanding ambiguities in prior frameworks.

Toward Large Nonradiating Qubits: When Quantum Engineering Meets Photonics

Advanced Quantum Technologies, Volume 9, Issue 3, March 2026.
Nonradiating superconducting qubits suppress radiative losses through photonic‐inspired mechanisms such as anapole states and bound states in the continuum (BICs). This review surveys theoretical foundations and recent implementations of large, wavelength‐scale qubits that confine electromagnetic energy while maintaining coherence.

Confined Chemistry in Space: Zeolite‐Supported Fe13 Nanoclusters Modulate CS Reactivity

Small Structures, Volume 7, Issue 3, March 2026.
The study explores how an Fe13 cluster confined in chabazite reshapes the reaction of CS and H2 under astrochemical conditions. Confinement promotes C–S bond cleavage over hydrogenation, directing chemistry toward CH4 and H2S formation. Additional CS enables CS2 and C2 species. Microkinetic analysis identifies protoplanetary environments where zeolites

The Post‐2020 Surge in Global Atmospheric Methane Observed in Ground‐Based Observations

Earth and Space Science, Volume 13, Issue 3, March 2026.
Abstract Methane (CH4) is a potent greenhouse gas with high radiative forcing and a relatively short atmospheric lifetime of around a decade. We used a decade‐long data set (2011–2022) from the Fourier transform spectrometer at the California Laboratory for Atmospheric Remote Sensing (CLARS‐FTS) to quantify a dramatic increase in methane observed in ...
