Orbital angular momentum conservation in Brillouin light scattering within a ferromagnetic sphere

open access: yesNew Journal of Physics, 2018
Magnetostatic modes supported by a ferromagnetic sphere have been known as the Walker modes, each of which possesses an orbital angular momentum as well as a spin angular momentum along a static magnetic field.

Brown Dwarfs and the Cataclysmic Variable Period Minimum [PDF]

open access: yes, 1999
Using improved, up-to-date stellar input physics tested against observations of low-mass stars and brown dwarfs we calculate the secular evolution of low-mass donor cataclysmic variables (CVs), including those which form with a brown dwarf donor.

Normal Form Near Orbit Segments of Convex Hamiltonian Systems

open access: yesInternational Mathematics Research Notices, 2021
Abstract In the study of Hamiltonian systems on cotangent bundles, it is natural to perturb Hamiltonians by adding potentials (functions depending only on the base point). This led to the definition of Mañé genericity [8]: a property is generic if, given a Hamiltonian $H$, the set of potentials $g$ such that $H+g$ satisfies the property ...

Origin, fate and homology of the precarotid plate in Pterocles alchata caudacutus

open access: yesJournal of Basic and Applied Zoology, 2012
A peculiar median transitory cartilaginous precarotid plate is developed forming a floor to the hypophyseal fenestra in the posterior orbital region of the intermediate developmental embryos of Pterocles alchata.

Nano-shaping of chiral photons

open access: yesNanophotonics, 2023
Localized surface plasmon polaritons can confine the optical field to a single-nanometer-scale area, strongly enhancing the interaction between photons and molecules. Theoretically, the ultimate enhancement might be achieved by reducing the “photon size”

Gutzwiller density functional calculations of the electronic structure of FeAs-based superconductors: Evidence for a three-dimensional Fermi surface

open access: yes, 2009
The electronic structures of FeAs-compounds strongly depend on the Fe-As bonding, which can not be described successfully by the local density approximation (LDA).

Architecture of Planetary Systems Based on Kepler Data: Number of Planets and Coplanarity

open access: yes, 2012
We investigated the underlying architecture of planetary systems by deriving the distribution of planet multiplicity (number of planets) and the distribution of orbital inclinations based on the sample of planet candidates discovered by the Kepler ...

Lattice-form-dependent orbital shape and charge disproportionation in charge- and orbital-ordered manganites [PDF]

open access: yesPhysical Review B, 2009
The orbital shapes and charge disproportionations at nominal Mn$^{3+}$ and Mn$^{4+}$ sites for the charge- and orbital-ordered phases have been studied on half-doped manganites Pr(Sr$_{0.1}$Ca$_{0.9}$)$_2$Mn$_2$O$_7$ and Eu$_{0.5}$Ca$_{1.5}$MnO$_4$ with double-layer and single-layer Mn-O networks, respectively, by means of x-ray structural analyses, in
