Abstract

N-soliton 火车在一个应用联合外部潜力套住描述 Bose 爱因斯坦冷凝物(BEC ) 的动力学的使不安的复杂 Toda 链(PCTC ) 的一个模型由弱泛音和倾斜的周期的部件组成首先被开发。用发达理论， BEC N-soliton 火车动力学被显示被 4N 很好接近联合非线性的微分方程，它在从振幅，速度， centre-of-mass 位置，和阶段的相互影响产生的系统描述基本相互作用。简化分析理论允许为描绘 BEC N-soliton 火车行为的一个有效、方便的方法。它进一步给为的潜力或更局部性的状态罐头的力量的批评价值从一列 soliton 火车被提取并且证明 BEC N-soliton 火车能由简单地操作潜力的力量从一个格子地点有选择地搬到另外一个。

Optical computing with soliton trains in Bose–Einstein condensates

Florian Pinsker

Optical computing devices can be implemented based on controlled generation of soliton trains in single and multicomponent Bose–Einstein condensates (BEC). Our concepts utilize the phenomenon that the frequency of soliton trains in BEC can be governed by changing interactions within the atom cloud [F. Pinsker, N. G. Berloff and V. M. Pérez-García, Phys. Rev. A87, 053624 (2013), arXiv:1305.4097]. We use this property to store numbers in terms of those frequencies for a short time until observation. The properties of soliton trains can be changed in an intended way by other components of BEC occupying comparable states or via phase engineering. We elucidate, in which sense, such an additional degree of freedom can be regarded as a tool for controlled manipulation of data. Finally, the outcome of any manipulation made is read out by observing the signature within the density profile.

Controlled manipulation of Bose-Einstein condensate solitons in complex potentials

Feng-De Zong

An extended variation method for describing the dynamical evolution of Bose-Einstein condensate solitons in the presence of optic-lattice and harmonic potentials was developed.This method agreed well with full numerical simulations and highlighted the dominant physical interactions in the system,namely,amplitude,width,chirp,center-position,and center-frequency dynamics.It further presented the critical strength ratio of optic-lattice to harmonic potential necessary to support multiple stable lattice sites for the Bose-Einstein condensate solitons and demonstrated that the Bose-Einstein condensate solitons could move selectively from one stable lattice site location to arbitrary final position by simply manipulating the optic-lattice potential.In addition,some interesting results for the experiments and applications of the Bose-Einstein condensates were also obtained.
