Efficient conversion of orbital Hall current to spin current for spin-orbit torque switching [PDF]
Communications Physics, 2021 Spin Hall effect, an electric generation of spin current, allows for efficient control of magnetization. Recent theory revealed that orbital Hall effect creates orbital current, which can be much larger than spin-Hall-induced spin current.

Detection of the Schwarzschild precession in the orbit of the star S2 near the Galactic centre massive black hole [PDF]
Astronomy & Astrophysics, 2020 The star S2 orbiting the compact radio source Sgr A* is a precision probe of the gravitational field around the closest massive black hole (candidate). Over the last 2.7 decades we have monitored the star’s radial velocity and motion on the sky, mainly ...

The Low Earth Orbit Satellite Population and Impacts of the SpaceX Starlink Constellation [PDF]
Astrophysical Journal, 2020 I discuss the current low Earth orbit artificial satellite population and show that the proposed “megaconstellation” of circa 12,000 Starlink Internet satellites would dominate the lower part of the Earth orbit, below 600 km, with a latitude-dependent ...

Maximizing Spin-Orbit Torque Generated by the Spin Hall Effect of Pt [PDF]
, 2021 Efficient generation of spin-orbit torques is central for the exciting field of spin-orbitronics. Platinum, the archetypal spin Hall material, has the potential to be an outstanding provider for spin-orbit torques due to its giant spin Hall conductivity,

Spin–orbit-coupled Bose–Einstein condensates [PDF]
Nature, 2011 Spin–orbit (SO) coupling—the interaction between a quantum particle’s spin and its momentum—is ubiquitous in physical systems. In condensed matter systems, SO coupling is crucial for the spin-Hall effect and topological insulators; it contributes to the ...
