Magnetic Precursor to the Structural Phase Transition in V2O3

Advanced Electronic Materials, EarlyView.
V₂O₃, a model Mott insulator, undergoes a metal‐insulator transition linked to structural and magnetic transitions, though the underlying mechanism remains unclear. Through muon‐spin rotation and X‐ray diffraction on strain‐engineered thin films, a magnetic precursor to the structural transition is identified, emphasizing the key role of magnetism in ...

New Light on Dark Extended Lenses with the Roman Space Telescope

The Astrophysical Journal Letters
The Roman Space Telescope’s Galactic Bulge Time Domain Survey will constitute the most sensitive microlensing survey of the Galactic bulge to date, opening up new opportunities to search for dark matter (DM). Many extensions of the Standard Model predict

Nonlinear Optical Imaging of Entangled Heterophase Polydomains in Ferroelectric BZT Films

Advanced Electronic Materials, EarlyView.
A non‐destructive, label‐free nonlinear optical imaging methodology is presented for the characterization of heterophase polydomains in ferroelectric materials. Through advanced second‐harmonic generation microscopy, tetragonal and rhombohedral domain structures are visualized directly, and local strain distributions in BaZr₀.₂Ti₀.₈O₃ films are ...

Maser Investigation toward Off-Plane Stars (MIOPS): Detection of SiO Masers in the Galactic Thick Disk and Halo

The Astrophysical Journal
Studying stars that are located off the Galactic plane is important for understanding the formation history of the Milky Way. We searched for SiO masers toward off-plane O-rich asymptotic giant branch (AGB) stars from the catalog presented by Mauron et ...

Determining Exciton Diffusion Length in Organic Semiconductors: Unifying Macro‐ and Microscopic Perspectives

Advanced Energy Materials, EarlyView.
Exciton diffusion length in organic semiconductor films is determined from encounter/annihilation rates. Non‐normalized exciton densities and proper intrinsic lifetime reference avoid over‐parametrization of the fits. Monte Carlo Simulation of individual molecule‐to‐molecule hops reproduce these results (②) when matching lattice constant and hoping ...
