Ferrimagnetic Dynamics Induced by Spin‐Orbit Torques
Advanced Materials Interfaces, 2022 Ferrimagnets are the magnetic materials with the fastest current‐induced dynamics reported so far. Among them, rare‐earth transition‐metal (RE‐TM) alloys offer a fertile playground for studying the behavior of multi‐sublattice systems with tunable ...

On the global dynamics of periodic triangular maps [PDF]
, 2016 This paper is an extension of an earlier paper that dealt with global dynamics in autonomous triangular maps. In the current paper, we extend the results on global dynamics of autonomous triangular maps to periodic non-autonomous triangular maps. We show

Magnetic Interactions in Orbital Dynamics
The Astronomical Journal, 2022 Abstract The magnetic field of a host star can impact the orbit of a stellar partner, planet, or asteroid if the orbiting body is itself magnetic or electrically conducting. Here, we focus on the instantaneous magnetic forces on an orbiting body in the limit where the dipole approximation describes its magnetic properties as well as ...

The Perturbed Full Two-body Problem: Application to Post-DART Didymos
The Planetary Science Journal, 2023 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.

Curvature in orbital dynamics [PDF]
American Journal of Physics, 2005 The physical basis and the geometrical significance of the equation for the orbit of a particle moving under the action of external forces is exhibited by deriving this equation in a coordinate-independent representation in terms of the radius of curvature of the orbit.

Robotic Manipulation and Capture in Space: A Survey
Frontiers in Robotics and AI, 2021 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
International Journal of Rotating Machinery, 2000 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]
, 2017 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
New Journal of Physics, 2018 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.
