Scattering of a dipole by a dipole

Solid State Communications, 1982
Abstract The spectrum of eigenvalues of the Schrodinger equation with a dipole-dipole potential is not bounded below. An appropriate cut-off leads to a correct low energy problem. Furthermore, it is shown that in polar coordinates the corresponding Schrodinger equation is separable for two spins 1/2.

Resonant dipole-dipole interaction in a cavity

Physical Review A, 1995
Resonant dipole-dipole interaction (RDDI) in a Fabry-P\'erot cavity is studied by the mode-expansion method. It is shown that the RDDI depends upon three factors: the length of the cavity, the positions of molecules, and the polarization of dipoles.

Rectangular dipoles in the discrete dipole approximation

Journal of Quantitative Spectroscopy and Radiative Transfer, 2015
Abstract We performed a comprehensive analysis of the extension of the discrete dipole approximation (DDA) to a rectangular cuboid lattice of dipoles. The theoretical analysis of two different approaches, based either on the point–dipole interaction or on the integration of Green׳s tensor (IGT), was performed starting with the rigorous integral ...

Dipole−Dipole Interactions in Nanoparticle Superlattices

Nano Letters, 2007
Nanoparticles often self-assemble into hexagonal-close-packed (hcp) structures although it is predicted to be less stable than face-centered-cubic (fcc) packing in hard-sphere models. In addition to close-packed fcc and hcp superlattices, we observe formation of nonclose-packed simple-hexagonal (sh) superlattices of nearly spherical PbS, PbSe, and ...

Magnetic field of a dipole and the dipole–dipole interaction

European Journal of Physics, 2007
With a data-acquisition system and sensors commercially available, it is easy to determine magnetic fields produced by permanent magnets and to study the dipole–dipole interaction for different separations and angular positions of the magnets. For sufficiently large distances, the results confirm the 1/R3 law for the magnetic field and the 1/R4 law for

DIPOLE-DIPOLE INTERACTION IN A SUPERCONDUCTOR

Modern Physics Letters B, 1994
Based on the London theory and the Pippard theory of superconductivity, we have calculated the magnetic induction distribution from a magnetic dipole located in a superconductor. The results have been used to evaluate the interaction energy between two magnetic dipoles located in the superconductor. The relevant applications of these calculations have

Noncovalently bound complexes of polar molecules: dipole-inside-of-dipole vs. dipole–dipole systems

New Journal of Chemistry, 2017
Complexes of polar molecules framed by counter-ions exhibit significant stabilities, huge dipole moments, prominent IR-spectral signatures and feasible anion-mediated formation.
