摘要

我们考虑准一维玻色-爱因斯坦凝聚，并在框架信息理论的方法下研究了物质波亮孤子的性质。在可忽略捕获效应的极限下，计算了不同平均场相互作用下的Shannon熵、Fisher信息和R{'e}nyi熵，并研究了群速度色散与非线性原子相互作用之间的相互作用。我们发现，信息论方法可以清楚地揭示物质波密度分布的局域性和离域性。在所有的情况下，发现熵不确定性是满足的。

Information measures on matter-wave solitons in Bose-Einstein condensates

We consider quasi-one-dimensional Bose-Einstein condensates and study the properties of matter-wave bright solitons within the framework information theoretic approach. In the limit of negligible trapping effect, we calculate Shannon entropy, Fisher information and R{'e}nyi entropy for different mean-field interaction, and study the interplay between group velocity dispersion and nonlinear atomic interaction. We see that information theoretic approach can clearly reveal localization and delocalization properties of matter-wave density distribution. In all the cases, entropic uncertainties are found to be satisfied.
