We study the onset of spin superfluidity, namely coherent transport mediated by a topological texture, in frustrated exchange-dominated magnetic systems, engendered an external field. show that for typical device geometries used nonlocal magnetotransport experiments, field stabilizes superflow against fluctuations, up to critical current. For given current, depends on precessional frequency whi...
A novel approach is proposed for the attitude stabilization and reorientation of an axi-symmetric spacecraft subject to two gas jet actuators. The approach is based on a new formulation of the attitude kinematics. Abstract| In this paper we consider the problem of attitude stabilization of an axi-symmetric spacecraft using two pairs of gas jet actuators. These actuators provide control torques ...
The realization of spin-orbit coupled systems by way of laser-induced Raman transitions in ultracold atoms gives an invaluable approach to simulate quantum many body physics. In order to realize such phenomena in the lab, these systems must be coherent. We create a negative feedback phase stabilization interferometer in order to achieve coherence between two beams for use in spinorbit coupling ...
Excitation of magnetization dynamics by pure spin currents has been recently recognized as an enabling mechanism for spintronics and magnonics, which allows implementation of spin-torque devices based on low-damping insulating magnetic materials. Here we report the first spatially-resolved study of the dynamic modes excited by pure spin current in nanometer-thick microscopic insulating Yttrium ...
