The evolution of the solar wind. [PDF]
Living Rev Sol Phys, 2021 How has the solar wind evolved to reach what it is today? In this review, I discuss the long-term evolution of the solar wind, including the evolution of observed properties that are intimately linked to the solar wind: rotation, magnetism and activity ...

In-situ Switchback Formation in the Expanding Solar Wind [PDF]
Astrophysical Journal, 2020 Recent near-Sun solar-wind observations from Parker Solar Probe have found a highly dynamic magnetic environment, permeated by abrupt radial-field reversals, or “switchbacks.” We show that many features of the observed turbulence are reproduced by a ...

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 ...

Mathematical Biosciences and Engineering, 2022 This paper investigates a left-hand circularly polarized (LHCP) antenna and a right-hand circularly polarized (RHCP) antenna on LEO Satellite, which is based on the phase-tuning metasurface. We overcome its inherent limitations in size, weight and power,
