Time‐Modulated Optomechanics Reveal Energy Flow and Inelastic Interactions Between Acoustic Phonons in Nanomembranes

Laser &Photonics Reviews, EarlyView.
Temporal interfaces are abrupt refractive index changes used in time‐varying optics, but also transitions to nonequilibrium states. This work explores the inelastic scattering of time‐varying light by nonthermal acoustic phonons in the vicinity of temporal interfaces.

PARCE: Accurate Inference of Crystal Structure Information From Phonon Vibrational Modes

Materials Genome Engineering Advances, EarlyView.
In this work, we introduce a multidescriptor framework and accuracy‐adaptive ensemble network to classify over 30,000 crystals from phonon and Raman data, achieving > 60% accuracy across diverse structures. Our work reduces reliance on ideal XRD data, enabling automated and large‐scale material structure analysis.

Light‐Driven Phase Engineering in 2D Materials From Mechanistic Assignment to Ambient Near‐Field Control

Small, EarlyView.
Light‐driven phase engineering in 2D materials centers on identifying what initiates conversion and what stabilizes the resulting phase. A practical workflow combines material verification, controlled driver tests, temporal measurements, and retention analysis.

Scalable Room‐Temperature Terahertz Graphene Cameras

Small Methods, EarlyView.
ABSTRACT Terahertz (THz) imaging has emerged as a powerful tool for non‐destructive, label‐free analysis across several scientific disciplines, ranging from materials science to biomedical research. By capturing the spatial‐dependent information in a broad range of frequencies, this technique enables the identification of chemical composition ...
