Excitation of coupled spin-orbit dynamics in cobalt oxide by femtosecond laser pulses. [PDF]
Nat Commun, 2017 Ultrafast control of magnets using femtosecond light pulses attracts interest regarding applications and fundamental physics of magnetism. Antiferromagnets are promising materials with magnon frequencies extending into the terahertz range.

Coupled attitude-orbit dynamics and control for an electric sail in a heliocentric transfer mission. [PDF]
PLoS One, 2015 The paper discusses the coupled attitude-orbit dynamics and control of an electric-sail-based spacecraft in a heliocentric transfer mission. The mathematical model characterizing the propulsive thrust is first described as a function of the orbital ...

Orbital Dynamics in Centrosymmetric Systems [PDF]
Phys. Rev. Lett. 128, 176601 (2022), 2021 Orbital dynamics in time-reversal-symmetric centrosymmetric systems is examined theoretically. Contrary to common belief, we demonstrate that many aspects of orbital dynamics are qualitatively different from spin dynamics because the algebraic properties of the orbital and spin angular momentum operators are different.

Orbit Dynamics for Unstable Linear Motion [PDF]
Proceedings of the 1997 Particle Accelerator Conference (Cat. No.97CH36167), 1996 A treatment is given of the orbit dynamics for linear unstable motion that allows for the zeros in the beta function and makes no assumptions about the realness of the betatron and phase functions. The phase shift per turn is shown to be related to the beta function and the number of zeros the beta function goes through per turn.

Orbit Dynamics and Kinematics with Full Quaternions [PDF]
IFAC Proceedings Volumes, 2004 Abstract Full quaternions constitute a compact notation for describing the motion of a body in the space. An important result about full quaternions is that they can be partitioned into a unit quaternion (which describes the orientation with respect to a suitable reference), and a modulus (which represents the translational motion along the direction

Terahertz oscillation driven by optical spin-orbit torque. [PDF]
Nat CommunAntiferromagnets are promising for nano-scale oscillator in a wide frequency range from gigahertz up to terahertz. Experimentally realizing antiferromagnetic moment oscillation via spin-orbit torque, however, remains elusive.

Single-shot dynamics of spin–orbit torque and spin transfer torque switching in three-terminal magnetic tunnel junctions [PDF]
Nature Nanotechnology, 2020 Current-induced spin-transfer torques (STT) and spin–orbit torques (SOT) enable the electrical switching of magnetic tunnel junctions (MTJs) in non-volatile magnetic random access memories.

Some Special Types of Orbits around Jupiter
Aerospace, 2021 This paper intends to show some special types of orbits around Jupiter based on the mean element theory, including stationary orbits, sun-synchronous orbits, orbits at the critical inclination, and repeating ground track orbits.

International Journal of Aerospace Engineering, 2023 For space robots, it is difficult to track continuous time-varying manifolds on SE(3) by using traditional closed-loop control strategies, which are designed to track the position and the attitude separately.
