Leaky Topological Edge State Cavities for On‐Chip Terahertz Sensing

Laser &Photonics Reviews, EarlyView.
Engineering radiation leakage in topological edge state cavities (TESCs) turns a conventional loss channel into a resource for enhancing on‐chip terahertz‐matter interactions. Tailoring the radiation leakage of a valley photonic crystal produces guided TESC with loaded Q factors up to 14 148 and leaky TESC with 2.2‐fold higher sensitivity, reaching 150.

Chip‐Scale Terahertz Sensing Driven by Supercoupling Induced Transparency in Topological Cavities

Laser &Photonics Reviews, EarlyView.
Supercoupling‐induced transparency (SIT) in topological cavities enables sensitive terahertz sensing on a chip. Strong field confinement and slow light response enhance interactions with thin films, enabling thickness detection through resonance shifts and group delay changes.

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.

Unraveling the Mechanism for Phonon Based Heat Transport in Metal‐Organic Frameworks

Small, EarlyView.
Heat transport in metal‐organic frameworks arises from an interplay between particle‐like phonon propagation and wave‐like inter‐band coupling. Using machine‐learned potentials within a unified phonon‐transport framework based on the Wigner transport theory, we reveal how differences in phonon lifetimes and phonon tunneling effects determine the ...

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.
