Orbital torque: Torque generation by orbital current injection

open access: yesPhysical Review Research, 2020
We propose a mechanism of torque generation by injection of an orbital current, which we call orbital torque. In a magnetic bilayer consisting of a nonmagnet (NM) and a ferromagnet (FM), we consider a situation where the spin-orbit coupling (SOC) is ...

Model study of the electron-phonon coupling in graphene; relative importance of intraband and interband scattering

open access: yes, 2016
The aim of this model study of the electron-phonon coupling in graphene was to find out about the relative importance of the inter- and intraband scattering and which phonon modes are the most active.

Higher orbital integrals, Shalika germs, and the Hochschild homology of Hecke algebras

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2001
We give a detailed calculation of the Hochschild and cyclic homology of the algebra 𝒞c∞(G) of locally constant, compactly supported functions on a reductive p-adic group G. We use these calculations to extend to arbitrary elements the definition

CEPHEID RADIAL VELOCITIES

open access: yesOdessa Astronomical Publications, 2017
Some results of the programme of the measurements of the Cepheid radial velocities by using a correlational spectrometer are presented. The spectral binarity of the classical Cepheids MW Cyg and VZ Cyg is discovered.

Proper Motion and Secular Variations of Keplerian Orbital Elements

open access: yesFrontiers in Astronomy and Space Sciences, 2018
High-precision observations require accurate modeling of secular changes in the orbital elements in order to extrapolate measurements over long time intervals, and to detect deviation from pure Keplerian motion caused, for example, by other bodies or ...

Orbit Determination from Tracking Data of Artificial Satellite Using the Method of Differential Correction [PDF]

open access: yesJournal of Astronomy and Space Sciences, 1988
The differential correction process determining osculating orbital elements as correct as possible at a given instant of time from tracking data of artificial satellite was accomplished.

Long term frequency stability analysis of the GPS NAVSTAR 6 Cesium clock [PDF]

open access: yes, 1982
Time domain measurements, taken between the NAVSTAR 6 Spacecraft Vehicle (SV) and the Vandenberg Global Positioning System (GPS) Monitor Site, by a pseudo random noise receiver, were collected over an extended period of time and analyzed to estimate the ...
