Magnetic Precursor to the Structural Phase Transition in V2O3
Advanced Electronic Materials, Volume 11, Issue 12, August 6, 2025.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 ...

Checking T and CPT violation with sterile neutrino
Nuclear Physics B, 2016 Post LSND results, sterile neutrinos have drawn attention and motivated the high energy physics, astronomy and cosmology to probe physics beyond the standard model considering minimal 3+1 (3 active and 1 sterile) to 3+N neutrino schemes.

Two Micron‐Size Dark Dimensions
Fortschritte der Physik, Volume 73, Issue 8, August 2025.Abstract Two extra dimensions of micron scale might simultaneously address the gauge and cosmological hierarchy problems. In this paper various observational bounds in scenarios with one and two large extra dimensions are examined, to see if they are compatible with the micron scale.

Multi‐Source Forecast of Solar Cycle Flare Activity Using the Novel Informer‐Based Models
Space Weather, Volume 23, Issue 4, April 2025.Abstract Solar flares, the significant indicators of solar activity, have an impact on Earth's satellites and communication systems. Accurate prediction of solar flare events is crucial for mitigating these effects. In this work, we use multiple data sources, including Geostationary Operational Environmental Satellites soft X‐ray flare flux and the ...

Geophysical Research Letters, Volume 52, Issue 6, 28 March 2025.Abstract Terrestrial gamma‐ray flashes (TGFs) are short bursts of intense gamma radiation associated with lightning discharges. Although thousands of TGFs have been observed from space, TGFs detected at ground level, known as downward TGFs, are still very limited, and their relationship with lightning discharge processes remains elusive. Here we report
