Dipole-Dipole Interactions Between Neutrons [PDF]

, 2020
In this work we present results of the dipole-dipole interactions between two neutrons, a neutron and a conducting wall, and a neutron between two walls. As input, we use dynamical electromagnetic dipole polarizabilities fitted to chiral EFT results up to the pion production threshold and at the onset of the Delta resonance. Our work can be relevant to

Dipole blockade without dipole-dipole interaction [PDF]

arXiv, 2021
The dipole blockade phenomenon is a direct consequence of strong dipole-dipole interaction, where only single atom can be excited because the doubly excited state is shifted out of resonance. The corresponding two-body entanglement with non-zero concurrence induced by the dipole blockade effect is an important resource for quantum information ...

Dynamics of Entanglement and Bell-nonlocality for Two Stochastic Qubits with Dipole-Dipole Interaction [PDF]

J. Phys. A: Math. Theor. 43 (2010) 415306, 2010
We have studied the analytical dynamics of Bell nonlocality as measured by CHSH inequality and entanglement as measured by concurrence for two noisy qubits that have dipole-dipole interaction. The nonlocal entanglement created by the dipole-dipole interaction is found to be protected from sudden death for certain initial states.

Color Dipole Systematics of the Diffraction Slope in Diffractive Photo- and Electroproduction of Vector Mesons [PDF]

Phys.Lett.B497:235-242,2001, 2000
We present the first evaluation of the color dipole diffraction slope from the data on diffractive photo- and electroproduction of vector mesons. The energy and dipole size dependence of the found dipole diffraction slope are consistent with the color dipole gBFKL dynamics.

Holographic Pomeron: Saturation and DIS [PDF]

, 2012
We briefly review the approach to dipole-dipole scattering in holographic QCD developed in ARXIV:1202.0831. The Pomeron is modeled by exchanging closed strings between the dipoles and yields Regge behavior for the elastic amplitude. We calculate curvature corrections to this amplitude in both a conformal and confining background, identifying the ...

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

, 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 attractive potential minimum in a pancake-shaped cloud.

Vortex Dipole in a BEC with dipole-dipole interaction [PDF]

arXiv, 2011
We consider single and multiply charged quantized vortex dipole in an oblate dipolar Bose Einstein condensate in the Thomas-Fermi (TF) regime. We calculate the critical velocity for the formation of a pair of vortices of opposite charge. We find that dipolar interactions decrease the critical velocity for a vortex dipole nucleation.

Radiation Reaction fields for an accelerated dipole for scalar and electromagnetic radiation [PDF]

, 1998
The radiation reaction fields are calculated for an accelerated changing dipole in scalar and electromagnetic radiation fields. The acceleration reaction is shown to alter the damping of a time varying dipole in the EM case, but not the scalar case. In the EM case, the dipole radiation reaction field can exert a force on an accelerated monopole charge ...

Dipole-dipole interaction in random electromagnetic fields [PDF]

Optics Letters, 2013
We demonstrate that a non-vanishing interaction force exists between pairs of induced dipoles in random, statistically stationary electromagnetic field. This new type of optical binding force leads to long-range interaction between dipolar particles even when placed in spatially incoherent fields.

Dipole blockade through Rydberg Forster resonance energy transfer [PDF]

arXiv, 2006
High resolution laser excitation of np Rydberg states of cesium atoms shows a dipole blockade at F\"{o}rster resonances corresponding to the resonant dipole-dipole energy transfer of the np + np → ns + (n + 1)s reaction. The dipole-dipole interaction can be tuned on and off by the Stark effect, and such a process observed for relatively low n (25 − 41)
