LLM‐Assisted Design of Ultralow‐κ$\kappa$ Chalcogenides

Advanced Science, EarlyView.
An AI assisted, physics guided workflow accelerates the discovery of ultralow thermal conductivity materials by combining Bayesian optimization, evidence conditioned LLM reasoning, and automated physics‐based validation. The framework uncovers dynamically stable Ag based chalcogenides with ultralow thermal conductivity and promising thermoelectric ...

Targeted Mechanogenetics to Modulate Specific Deep Neural Circuits

Advanced Science, EarlyView.
This study introduces mechanogenetics, a nanobubble‐enhanced sonogenetic strategy for selective modulation of feeding‐related neural circuits in the mouse lateral hypothalamus. Mechanogenetic stimulation modulates feeding behavior through glutamatergic projections from the lateral hypothalamus to the ventral tegmental area, highlighting its potential ...

Optical Access to Dark Excitons Via Spin–Phonon Fano Interference

Advanced Science, EarlyView.
Dark excitons in quantum dots neither absorb nor emit light and stay hidden from optical spectroscopy. Quantum interference now reveals them: light scattered by acoustic phonons interferes with a phonon‐assisted spin flip between bright and dark exciton, carving a Fano dip into the spectrum whose position gives the bright–dark splitting. Magnetic field,

Chiral‐Nematic Lattice Instability in Charge Density Wave of 1T‐TiSe2

Advanced Science, EarlyView.
The charge density wave of 1T‐TiSe2 appears chiral to surface probes yet loses all symmetry in spectroscopic measurements. This study reveals how cooperative condensation of multiple phonon modes stabilizes a chiral monoclinic ground state, while a shallow nematic energy landscape allows the lattice to break the remaining symmetry at negligible cost ...

Interfacial Reconstruction Enables Enhanced Thermoelectric Performance in Bismuth Telluride‐Based Alloys

Advanced Science, EarlyView.
Bismuth telluride‐based alloys are benchmark thermoelectric materials for near‐room‐temperature applications. Here, SnSe‐induced interfacial reconstruction simultaneously optimizes carrier and phonon transport in Bi0.4Sb1.6Te3, achieving a peak ZT of ∼1.38 at 363 K and a device efficiency of ∼6.47%, providing an effective strategy for high‐performance ...
