Observation of the orbital Hall effect in a light metal Ti [PDF]
Nature 619, 52-56 (2023), 2021 The orbital angular momentum is a core ingredient of orbital magnetism, spin Hall effect, giant Rashba spin splitting, orbital Edelstein effect, and spin-orbit torque. However, its experimental detection is tricky. In particular, direct detection of the orbital Hall effect remains elusive despite its importance for electrical control of magnetic ...

Orbit Dynamics in Isochronous Cyclotrons [PDF]
IEEE Transactions on Nuclear Science, 1981 Acceleration of heavy ions in an isochronous cyclotron can lead to a ..nu../sub r/-value near unity for many turns. In ORIC, several departures from 3-fold symmetry unfortunately exist, so that a complex resonant behavior may lead to beam loss. To study these questions, a program has been initiated with the aim of devising and using very efficient ...

Orbital and equilibrium dynamics of a multiwell potential
Results in Physics, 2022 We consider a Hamiltonian system associated with the two-well umbilical catastrophe potential D5, while the corresponding potential contains only one free parameter. We determine how this free parameter affects the equilibrium dynamics of the system by computing their coordinates on the configuration plane, along with their linear stability and type ...

Spin–Orbit Interactions Greatly Accelerate Nonradiative Dynamics in Lead Halide Perovskites
ACS Energy Letters, 2018 In this work, we study the role of spin–orbit coupling (SOC) in nonradiative relaxation of hot electrons and holes in methylammonium lead perovskite, MAPbI3.

Constructing a Low Energy Transfer Between Jovian Moons [PDF]
, 2001 There has recently been considerable interest in sending a spacecraft to orbit Europa, the smallest of the four Galilean moons of Jupiter. The trajectory design involved in effecting a capture by Europa presents formidable challenges to traditional ...

The catalogue of cometary orbits and their dynamical evolution [PDF]
Astronomy & Astrophysics, 2020 We present the CODE catalogue, the new cometary catalogue containing data for almost 300 long-period comets that were discovered before 2018. This is the first catalogue containing cometary orbits in the five stages of their dynamical evolution and covering three successive passages through the perihelion, with the exception of the hyperbolic comets ...

Solving Coplanar Power-Limited Orbit Transfer Problem by Primer Vector Approximation Method
International Journal of Aerospace Engineering, 2012 The coplanar orbit transfer problem has been an important topic in astrodynamics since the beginning of the space era. Though many approximate solutions for power-limited orbit transfer problem have been developed, most of them rely on simplifications of
