Twisted behavior of dipolar BECs: Dipole-dipole interaction beyond the self-consistent field approximation and exchange electric dipole interaction [PDF]

open access: yesarXiv, 2014
Dipole-dipole interaction is a long-range interaction, hence we could expect that the self-consistent field approximation might be applied. In most cases it is correct, but dipolar BECs reveal a surprise. Structure of the self-consistent field term requires that interacting particles are in different quantum states, while in BECs all particles in a ...

Circularly Polarized Yagi-Like Dipole Array Antenna Using Meander-Shaped Parasitic Element

open access: yesIEEE Access
This article proposes a new approach to designing dipole antennas that can create circular polarization. Using a meander-shaped parasitic element in the upper part of the dipole forms a Yagi-Uda-like structure, and the cooperation between the dipole and ...

Resonance interaction of two dipoles in optically active surroundings [PDF]

open access: yesarXiv, 2016
We study the resonance interaction between two quantum electric dipoles immersed in optically active surroundings. Quantum electrodynamics is employed to deal with dipole-vacuum interaction. Our results show that the optical activity of surroundings will not change the single atom behaviors while it can change the collective behaviors of the two ...

Modulating Diffusion Double Layer by In Situ Constructed Ultrathin Dipole Layer Towards Uniform Lithium Deposition

open access: yesBatteries
The popularization of lithium metal anode has been limited due to uneven deposition processes and lithium dendrites. Guiding homogeneous nucleation during the initial plating stage of lithium is vital to obtain a stable lithium metal anode.

Comparative Evolutionary Analysis of Dipole and Non-Dipole Components of Geomagnetic Energy

open access: yesУчёные записки Казанского университета: Серия Естественные науки
The total energy of the potential geomagnetic field (up to the core-mantle boundary) is divided into dipole and non-dipole parts, which are determined by their evolution and frequency properties. The calculations presented here are based on the available
