On the saturation of excitation-dependent dipole-dipole broadening in dense Rb vapour [PDF]

open access: yesE3S Web of Conferences
We study dependence of dipole-dipole interaction in dense Rb vapour on optical excitation. We measure the dipole-dipole contribution to the selective reflection spectrum of D2 line.

Stimulated dipole–dipole interaction: A highly efficient mechanism for amplifying light-generated effects [PDF]

open access: yesAIP Advances
A concept termed “stimulated dipole–dipole interaction” as a framework is proposed to describe coherence-enhanced light–matter interactions. Unlike conventional dipole–dipole interactions, excitation-induced dipoles, generated through external ...

All organic multiferroic magnetoelectric complexes with strong interfacial spin-dipole interaction

open access: yesnpj Flexible Electronics, 2021
The organic magnetoelectric complexes are beneficial for the development on flexible magnetoelectric devices in the future. In this work, we fabricated all organic multiferroic ferromagnetic/ferroelectric complexes to study magnetoelectric coupling at ...

Switchable high-Q electromagnetically induced transparency based on the Ge2Sb2Te5 nanodisk dimers

open access: yesResults in Physics, 2023
Bound states in the continuum (BICs) based on metasurfaces have gained significant attention recently to enhance the strength of light-matter interaction. However, most BIC metasurfaces possess fixed optical properties once they have been fabricated.

Dipole-dipole instability of atom clouds in a far-detuned optical dipole trap [PDF]

open access: yes, 2006
The effect of the dipole-dipole interaction on the far-off-resonance optical dipole trapping scheme is calculated by a mean-field approach. The trapping laser field polarizes the atoms and the accompanying dipole-dipole energy shift deepens the ...

Direct measurements of the colloidal Debye force

open access: yesNature Communications, 2023
Colloids often behave in a manner similar to their counterparts in molecular space and are used as model systems to understand molecular behavior. Here, we study like-charged colloidal attractions between a permanent dipole on an interfacial particle and

Dipole–dipole interactions in optical lattices do not follow an inverse cube power law

open access: yesNew Journal of Physics, 2013
We study the effective dipole–dipole interactions in ultracold quantum gases on optical lattices as a function of asymmetry in confinement along the principal axes of the lattice.

Dipole–dipole interaction in superparamagnetic nanocrystalline Fe63.5Cr10Si13.5B9Cu1Nb3 [PDF]

open access: yes, 2001
Cr-substituted Finemet-type nanocrystalline alloy (Fe63.5Cr10Si13.5B9Cu1Nb3) has been studied by differential scanning calorimetry, x-ray diffraction, Mo¨ssbauer spectroscopy, and magnetic measurements.

The interaction of dipole modifiers with polyene-sterol complexes. [PDF]

open access: yesPLoS ONE, 2012
Recently, we showed that the effect of dipole modifiers (flavonoids and styrylpyridinium dyes) on the conductance of single amphotericin B (AmB) channels in sterol-containing lipid bilayers primarily resulted from changes in the membrane dipole potential.

Resonant dipole–dipole interaction in confined and strong-coupling dielectric geometries

open access: yesNew Journal of Physics, 2013
Using the electromagnetic response function of an electric dipole located within a dielectric geometry, we derive the mathematical equivalence between the classical response and quantum mechanical resonant dipole–dipole interaction between two quantum ...
