Spin-torque efficiency enhanced by Rashba spin splitting in three dimensions

, 2012
We examine a spin torque induced by the Rashba spin-orbit coupling in three dimensions within the Boltzmann transport theory. We analytically calculate the spin torque and show how its behavior is related with the spin topology in the Fermi surfaces by ...

Stable Torque Optimization for Redundant Robots Using a Short Preview [PDF]

, 2019
We consider the known phenomenon of torque oscillations and motion instabilities that occur in redundant robots during the execution of sufficiently long Cartesian trajectories when the joint torque is instantaneously minimized.
