Modeling of Elves Doublets Based on Variations of the Lightning Return Stroke Current
Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.Abstract Elves are transient luminous events appearing above thunderclouds. They are produced by high peak current lightning events. They occasionally appear as doublets or in general as multiplets. We model elves doublets by setting the temporal and spatial variations of the return stroke current amplitude and we show that our modeling results are ...

Dynamic Holographic Display With Multiplexed Dielectric Metasurfaces
Nanophotonics, Volume 15, Issue 12, 25 June 2026.Based on multiplexed metasurfaces, we show hybrid multiplexing of polarization, wavelength, and orbital angular momentum can be applied for dynamic tuning. Our strategy presents a highly compact and efficient solution for high‐capacity, multi‐dimensional holography, with promising applications in advanced displays, data storage, optical encryption, and

Toward Reliable Spectroscopic Analysis of Reaction Kinetics in Polaritonic Chemistry
Nanophotonics, Volume 15, Issue 11, 13 June 2026.Vibrational strong coupling has been reported to modify chemical reaction rates, yet its mechanism remains unresolved. We expose pitfalls in UV/Vis‐based kinetic analyses and emphasize the need for standardized cavity protocols. ABSTRACT Recent reports suggest that chemical reaction rates can change inside an optical cavity.
