Oriented Aggregation

ABSTRACTIn order to study the oriented aggregation of BaTiO3nanocrystals in the ultrasound-assisted synthesis in an aqueous solution [F.Dang et al., Jpn.J.Appl.Phys. 48, 09KC02 (2009)], the electric dipole-dipole interaction model has been studied by numerical simulations. The results of the numerical simulations are consistent with the experimental ones if the electric dipole moment of a primary particle (a nanocrystal) of 5 nm in diameter is about 10 D =3.3 x 10-29 (C m). It suggests that a 5-10 nm BaTiO3 nanocrystal synthesized in an aqueous solution with ultrasound has spontaneous polarization.

Side Band

The fluorescence spectrum of a system of strongly driven atoms, contained in a region that is small compared with the wavelength, is calculated using a screened interaction model. Coulomb dipole–dipole interaction is neglected, but a Markov approximation is not made. The side bands at ω′ = ω ± Ω and ω ± 2Ω are investigated in detail (ω′(ω) is the emitted photon (pump field) frequency; Ω is the Rabi frequency). The intensity and line width of the side bands at ω ± 2Ω is reduced owing to S breaking in our model. Non-Markovian corrections split the side band at ω ± Ω.

Physical Dimensions

We have calculated the levitation force and interaction energy between a short magnetic bar and a superconducting cylinder in the Meissner state using the dipole–dipole interaction model. We derived analytical expression of the levitation force acting on the short magnet as a function of the orientation angle of magnetic dipole, and the physical dimensions of the magnet-superconductor system. The effects of the thickness of the superconductor and the length of the magnet on the levitation force were studied.
