Surface orbitronics: new twists from orbital Rashba physics [PDF]
Sci. Rep. 7, 46742 (2017), 2016 When the inversion symmetry is broken at a surface, spin-orbit interaction gives rise to spin-dependent energy shifts - a phenomenon which is known as the spin Rashba effect. Recently, it has been recognized that an orbital counterpart of the spin Rashba effect - the orbital Rashba effect - can be realized at surfaces even without spin- orbit coupling.

Reduction of Space Debris Collision Prediction Uncertainty Based on Q-Sat Precise Orbit
Space: Science & Technology, 2023 Collision probability is employed for evaluating whether there will be a dangerous encounter between 2 space objects. The fidelity of the collision probability mainly depends on the accuracies of orbit prediction and covariance prediction for the space ...

A Method to Determine BeiDou GEO/IGSO Orbital Maneuver Time Periods
Sensors, 2019 Because there are different types of BeiDou constellations with participating geostationary orbit (GEO) and inclined geosynchronous orbit (IGSO) satellites, the maneuvering frequency of BeiDou satellites is higher than that of other navigation systems ...

Orbital order in vanadium spinels [PDF]
Phys. Rev. B 72, 020408(R) (2005), 2005 Motivated by recent theoretical and experimental controversy, we present a theoretical study to clarify the orbital symmetry of the ground state of vanadium spinel oxides AV$_2$O$_4$ (A=Zn, Mg, Cd). The study is based on an effective Hamiltonian with spin-orbital superexchange interaction and a local spin-orbit coupling term.

Intrinsic Magnon Orbital Hall Effect in Honeycomb Antiferromagnets [PDF]
arXiv, 2023 We theoretically investigate the transport of magnon orbitals in a honeycomb antiferromagnet. We find that the magnon orbital Berry curvature is finite even without spin-orbit coupling and thus the resultant magnon orbital Hall effect is an intrinsic property of the honeycomb antiferromagnet rooted only in the exchange interaction and the lattice ...
