WebWhen you apply an electric field they develop a dipole moment: $\vec d=\alpha \vec E$. The coefficient $\alpha$ is the polarizability. Of course the potential energy of a dipole in an … WebIn this Letter, we show that a three-dimensional Bose-Einstein solitary wave can become stable if the dispersion law is changed from quadratic to quartic. We suggest a way to realize the quartic dispersion, using shake…

WebOptical lattices have developed into successful model systems for effects known or predicted in solid state physics 5 .Bloch oscillations, in which an atom subject to a force performs an oscillatory rather than a uniformly accelerated motion, are one of the most striking quantum transport property arising from the periodic potential 6 .In other works, … There are two important parameters of an optical lattice: the potential well depth and the periodicity. The potential experienced by the atoms is related to the intensity of the laser used to generate the optical lattice. The potential depth of the optical lattice can be tuned in real time by changing the power of the laser, which is normally controlled by an acousto-optic modulator (AOM). The AOM i…
WebRecently, new classes of optical lattices were identified, permitting the creation of arbitrarily large two- and three-dimensional arrays of tightly confined excitation maxima of controllable periodicity and polarization from the superposition of a finite set of plane waves.
