Spin-orbit torque-driven skyrmion dynamics revealed by time-resolved X-ray microscopy [PDF]
Magnetic skyrmions are topologically protected spin textures with attractive properties suitable for high-density and low-power spintronic device applications.

The Perturbed Full Two-body Problem: Application to Post-DART Didymos
With the successful impact of the NASA Double Asteroid Redirection Test (DART) spacecraft in the Didymos–Dimorphos binary asteroid system, we provide an initial analysis of the post-impact perturbed binary asteroid dynamics.

The Triaxiality Role in the Spin-Orbit Dynamics of a Rigid Body
We study the roto-orbital dynamics of a uniform sphere and a triaxial body by means of a radial intermediary, which defines a 2-DOF Hamiltonian system. Our analysis is carried out by using variables referred to the total angular momentum.

Robotic Manipulation and Capture in Space: A Survey
Space exploration and exploitation depend on the development of on-orbit robotic capabilities for tasks such as servicing of satellites, removing of orbital debris, or construction and maintenance of orbital assets. Manipulation and capture of objects on-

Thermal Bending of the Rotor Due to Rotor-to-Stator Rub
The rotor thermal bending due to the rotor-to-stator rubbing can lead to one of three types of observed rotor lateral motion: (1) spiral with increasing amplitude, (2) oscillating between rub]no-rub conditions, and (3) asymptotical approach to the rotor ...

Microscopic theory of spin-orbit torques and skyrmion dynamics [PDF]
We formulate a general microscopic approach to spin-orbit torques in thin ferromagnet/heavy-metal bilayers in linear response to electric current or electric field. The microscopic theory we develop avoids the notion of spin currents and spin-Hall effect.

Axial to transverse energy mixing dynamics in octupole-based magnetostatic antihydrogen traps
The nature of the trajectories of antihydrogen atoms confined in an octupole minimum-B trap is of great importance for upcoming spectroscopy, cooling, and gravity experiments.

Orbit Decomposition Method for Rotordynamic Coefficients Identification of Annular Seals
The elliptical orbit whirl model is widely used to identify the frequency-dependent rotordynamic coefficients of annular seals. The existing solution technique of an elliptical orbit whirl model is the transient computational fluid dynamics (CFD) method.

Simulation of Spin-orbit Dynamics in Storage Rings
In the article a mapping approach based on nonlinear matrix integration for longterm spin-orbit dynamics simulation is briefly described. Using this technique the nonlinear effects of spin dynamics in an electrostatics storage ring are investigated ...

Zero Average Surface Controlled Boost-Flyback Converter
The boost-flyback converter is a DC-DC step-up power converter with a wide range of technological applications. In this paper, we analyze the boost-flyback dynamics when controlled via a modified Zero-Average-Dynamics control technique, hereby named Zero-
