Orbital-polarization terms: From a phenomenological to a first-principles description of orbital magnetism in density-functional theory
(JOHN WILEY & SONS INC, 2008)
Phenomenological orbital-polarizition (OP) terms have been repeatedly introduced in the single-particle equations of spin-density-functional theory, in order to improve the description of orbital magnetic moments in systems ...
Intervening in Earth's climate system through space-based solar reflectors
(2016-07-01)
Several space-based climate engineering methods, including shading the Earth with a particle ring for active cooling, or the use of orbital reflectors to increase the total insolation of Mars for climate warming have been ...
On Polar Foliations and the Fundamental Group
(BIRKHAUSER VERLAG AG, 2011)
In this work we investigate the relation between the fundamental group of a complete Riemannian manifold M and the quotient between the Weyl group and reflection group of a polar action on M, as well as the relation between ...
FROZEN ORBITS AROUND EUROPA
(World Scientific Publ Co Pte Ltd, 2012-10-01)
Low-altitude, near-polar orbits are very desirable for scientific missions to study the natural satellites of the planets of the Solar System, such as Europa, that is one of the natural satellites of Jupiter. The problem ...
Orbital Angular Momentum Tuning Using a Phase Only Parallel Aligned LCoS Display
(Elsevier Gmbh, 2020-06)
We propose two schemes for achieving continuous and complete orbital angular momentum tuning using a simple device based on a phase only parallel aligned liquid crystal on silicon (PA-LCoS) display, where the tuning is ...
Polar foliations and isoparametric maps
(SPRINGERDORDRECHT, 2012-02)
A singular Riemannian foliation F on a complete Riemannian manifold M is called a polar foliation if, for each regular point p, there is an immersed submanifold Sigma, called section, that passes through p and that meets ...
Low-altitude, near-polar and near-circular orbits around Europa
(Elsevier B.V., 2012-03-01)
The dynamics of orbits around planetary satellites, taking into account the gravitational attraction of a third-body and the non -uniform distribution of mass of the planetary satellite, is studied. The Hamiltonian considered ...

A permanent magnet hall thruster for pulsed orbit control of lunar polar satellites
(2014-01-01)
Future Moon missions devoted to Lunar surface remote sensing, for example, will require very fine and accurate orbit control. It is well known that Lunar satellites in polar orbits will suffer a high increase on the ...
