Influence of internal structure on the motion of test bodies in extreme mass ratio situations

open access: yes, 2012
We investigate the motion of test bodies with internal structure in General Relativity. With the help of a multipolar approximation method for extended test bodies we derive the equations of motion up to the quadrupolar order.

From geodesics of the multipole solutions to the perturbed Kepler problem [PDF]

open access: yes, 2010
A static and axisymmetric solution of the Einstein vacuum equations with a finite number of Relativistic Multipole Moments (RMM) is written in MSA coordinates up to certain order of approximation, and the structure of its metric components is explicitly ...

QUADRUPOLE COUPLING CONSTANT AND ELECTRONIC STRUCTURE OF COMPOUNDS ЭХ3

open access: yesИзвестия высших учебных заведений: Проблемы энергетики, 2018
For the series of molecules type ЭХ3 (Э = N, As, Sb; X = F, Cl, Br, J) obtained quantitative relations between the values of the quadrupole coupling constants e2Qq and parameters J and μэ3-, characterizing the relative magnitude of the spatial ...

Abnormal field-dependence of magnetocaloric effect in ErB4 and TmB4

open access: yesAIP Advances, 2020
The coupled system of multi-degrees of freedom, such as charge, spin, orbital and lattice, has recently received much attention due to its potential to improve the magnetocaloric effect (MCE).

Energy distribution of an ion cloud in a quadrupole Penning Trap

open access: yesJournal of Nigerian Society of Physical Sciences, 2020
Ions are confined in Penning trap by the combination of electric field and magnetic field, as the electric field confines ions in the axial direction through an electric potential minimum and the magnetic field applied along the axis of the trap confines

Molecular electrostatic potentials from machine learning models for dipole and quadrupole predictions

open access: yesAI for Science
The molecular electrostatic potential (MEP) is a key quantity for describing and predicting intermolecular and ion–molecule interactions. Here, we assess the ability of machine-learning (ML) models to infer the MEP, based on the equivariant graph ...

Diagnosis of by carbon-13 urea breath test using a portable mass spectrometer

open access: yesSAGE Open Medicine, 2015
Context: In the non-invasive detection of markers of disease, mass spectrometry is able to detect small quantities of volatile markers in exhaled air. However, the problem of size, expense and immobility of conventional mass spectrometry equipment has ...

Three tests of general relativity via Fermat's principle and the phase of Bessel functions

open access: yes, 2003
Fermat's principle applied to a flat metric in the plane yields the phase of a Bessel function in the periodic domain for a constant index of refraction.

Shape transition and fluctuation in neutron-rich Cr isotopes around N = 40

open access: yes, 2012
The spherical-to-prolate shape transition in neutron-rich Cr isotopes from N = 34 to 42 is studied by solving the collective Schr\"odinger equation for the five-dimensional quadrupole collective Hamiltonian.
