Convex Regular Polychora Nanocrystals with Dipole–Dipole Interactions [PDF]
NanomaterialsStructures composed of classical dipoles in higher-dimensional space present a unique opportunity to venture beyond the conventional paradigm of few-body or cluster physics.

Polar form of spinor fields from regular to singular: the flag-dipoles [PDF]
European Physical Journal C: Particles and Fields, 2020 In this paper, we perform the polar analysis of the spinorial fields, starting from the regular cases and up to the singular cases: we will give for the first time the polar form of the spinorial field equations for the singular cases constituted by the ...

Open Journal of Physical Chemistry, 2019 Aim of this work is to try to explain, on a Rational basis, some equations of Electro-Magnetism, which are based on Experimental data. Any Electric Field can produce a Field of many small Electric Dipoles, continuously distributed in space. In a region, where the Electric Field is constant, in direction and magnitude, all the small Dipoles are parallel

Analytical Model for Regular Dense Arrays of Planar Dipole Scatterers [PDF]
Progress in Electromagnetics Research, 2002 An analytical boundary condition for modeling the electromagnetic properties of planar regular dense arrays of dipole particles for oblique incidence of plane waves is developed. The regular array is assumed to be dense which means that the dipole particles are close to each other.

On minimal energy dipole moment distributions in regular polygonal agglomerates
Journal of Magnetism and Magnetic Materials, 2017 Abstract Static, regular polygonal and close-packed clusters of spherical magnetic particles and their energy-minimizing magnetic moments are investigated in a two-dimensional setting. This study focuses on a simple particle system which is solely described by the dipole-dipole interaction energy, both without and in the presence of an in-plane ...

Fast near field calculations in the discrete dipole approximation for regular rectilinear grids
Optics Express, 2012 A near-field calculation of light electric field intensity inside and in the vicinity of a scattering particle is discussed in the discrete dipole approximation. A fast algorithm is presented for gridded data. This algorithm is based on one matrix times vector multiplication performed with the three dimensional fast Fourier transform.

A Model of Interacting Navier–Stokes Singularities
Entropy, 2022 We introduce a model of interacting singularities of Navier–Stokes equations, named pinçons. They follow non-equilibrium dynamics, obtained by the condition that the velocity field around these singularities obeys locally Navier–Stokes equations.

Regular and chaotic orbits near a massive magnetic dipole [PDF]
Classical and Quantum Gravity, 2012 Within the framework of Bonnor's exact solution describing a massive magnetic dipole, we study the motion of neutral and electrically charged test particles. In dependence on the Bonnor spacetime parameters, we determine regions enabling the existence of stable circular orbits confined to the equatorial plane and of those levitating above the ...
