Continuous evolution of Fermi arcs in a minimal ideal photonic Weyl medium

Light: Science & Applications
Propagation properties of electromagnetic waves in an optical medium are mainly determined by the contour of equal-frequency states in $${\boldsymbol{k}}$$ k -space.

Enhancing Corrosion Resistance and Mechanical Strength of 3D‐Printed Iron Polylactic Acid for Marine Applications via Laser Surface Texturing

Advanced Engineering Materials, EarlyView.
Laser surface texturing significantly improves the corrosion resistance and mechanical strength of 3D‐printed iron polylactic acid (Ir‐PLA) for marine applications. Optimal laser parameters reduce corrosion by 80% and enhance tensile strength by 25% and ductility by 15%.

Adjustable Plasmonic Core–Shell Nanoparticles for Personalized Color Vision Correction

Advanced Engineering Materials, EarlyView.
This study introduces a personalized solution for correcting color vision deficiency (CVD) by embedding tunable core‐shell metal nanoparticles—a common nanotechnology—into contact lenses. By customizing the nanoparticles’ optical properties to filter specific wavelengths, these lenses address individual visual impairments, enhancing color ...

Exceptional lines and higher-order exceptional points enabled by uniform loss

Scientific Reports
This study theoretically investigates the realization of exceptional points (EPs) in space-time invariant Lorentz dispersive media with uniform loss, which contrasts sharply with conventional approaches that rely on spatial or temporal differential ...

All-optical radio-frequency phase detection for Rydberg atom sensors using oscillatory dynamics [PDF]

arXiv
Rydberg atom radio frequency sensors are a unique platform for precision electromagnetic field measurement, e.g. they have extraordinary carrier bandwidth spanning MHz-THz and can be self-calibrated. These photonic sensors use lasers to prepare and read out the atomic response to a radio frequency electromagnetic field.

High‐Rate Deposition and Characterization Study of CoZrO Films for On‐Chip Power Applications

Advanced Engineering Materials, EarlyView.
This study introduces a high‐rate reactive sputtering process for CoZrO films, aimed at large‐scale production of on‐chip magnetic components compatible with complementary metal oxide semiconductor (CMOS) fabrication. Characterization of the deposited films reveals that ideal magnetic properties require chemical compositions in a narrow Co:O range and ...
