Dark Solar Wind

Physical Review Letters, 2022
We study the solar emission of light dark sector particles that self-interact strongly enough to self-thermalize. The resulting outflow behaves like a fluid which accelerates under its own thermal pressure to highly relativistic bulk velocities in the solar system.

The model for non-Abelian field topology for the multilayer fractional quantum anomalous Hall device

Frontiers in Physics, 2022
From the recent empirical discovery of the quantum anomalous Hall effect (QAHE), the interaction of the particle with spin–orbit coupling (SOC) plays an essential role in the cause of the QAHE, which includes three terms: external, internal, and chiral ...

Extension of PAR Models under Local All-Sky Conditions to Different Climatic Zones

Applied Sciences, 2022
Four models for predicting Photosynthetically Active Radiation (PAR) were obtained through MultiLinear Regression (MLR) and an Artificial Neural Network (ANN) based on 10 meteorological indices previously selected from a feature selection algorithm.
