Quantum Dust Cores of Black Holes and Their Quasi‐Normal Modes
We investigate the quasi‐normal mode spectrum of a gravitationally collapsed ball of dust, considering both a linear and a refined parabolic effective mass function for the quantum core. Furthermore, we account for the quantum leakage of dust particles outside the horizon.

A unified construction of finite geometries associated with q-clans in characteristic 2
Flocks of Laguerre planes, generalized quadrangles, translation planes, ovals, BLTsets, and the deep connections between them, are at the core of a developing theory in the area of geometry over finite fields.

Rayleigh and Raman optical activity using Laguerre-Gaussian twisted light
Chiral molecules scatter circularly-polarized light at different rates according to their handedness and that of the incident photons. A right-handed molecule, for example, scatters right-handed circularly-polarized light at a different rate to ...

Key distribution patterns using tangent circle structures
The problem of key management in a communications network is of primary importance. A key distribution pattern is an incidence structure which provides a secure method of distributing keys in a large network reducing storage requirements.

Incircular nets and confocal conics
We consider congruences of straight lines in a plane with the combinatorics of the square grid, with all elementary quadrilaterals possessing an incircle. It is shown that all the vertices of such nets (we call them incircular or IC-nets) lie on confocal

Third-harmonic generation microscopy with focus-engineered beams: a numerical study
International audienceWe use a vector field model to analyze third-harmonic generation (THG) from model geometries (interfaces, slabs, periodic structures) illuminated by Hermite-Gaussian (HG) and Laguerre-Gaussian (LG) beams focused by a high NA lens ...

Generation of axisymmetric modes in cylindrical kinematic mean-field dynamos of VKS type
International audienceIn an attempt to understand why the dominating magnetic field observed in the von-Kaacutermaacuten-sodium (VKS) dynamo experiment is axisymmetric, we investigate in the present article the ability of mean field models to generate ...

Laguerre Geometry of Hypersurfaces in $\R^n$
Laguerre geometry of surfaces in $\R^3$ is given in the book of Blaschke [1], and have been studied by E.Musso and L.Nicolodi [5], [6], [7], B. Palmer [8] and other authors. In this paper we study Laguerre differential geometry of hypersurfaces in $\R^n$.
