Amorphization-Mediated Si-I to Si-V Phase Transition and Reversible Amorphous-Si-V Phase Memory in Silicon Nanoparticles

Posted by klaurent Caltech

Kavli Affiliate: Wei Gao | First 5 Authors: Ziye Deng, Ziye Deng, , , | Summary: Molecular dynamics simulations using a Gaussian Approximation Potential (GAP) reveal a stress triaxiality driven, two-step Si-I (diamond cubic) to Si-V (simple hexagonal) phase transition pathway in a spherical Si nanoparticle with a 10 nm diameter under triaxial compression. A […]

Mitigating Random-Phase Sampling Noise in the Cepheid Period-Luminosity Relation: A Cross-Filter Consistency Approach

Posted by klaurent Chicago

Kavli Affiliate: Wendy L. Freedman | First 5 Authors: Mahdi Abdollahi, Mahdi Abdollahi, , , | Summary: The Period-Luminosity (PL) relation is usually derived using time-averaged magnitudes, which require multiple-epoch observations to determine periods and adequately sample the light curves. Although single-epoch observations are more practical and require significantly less observational effort, they inherently introduce […]
