摘要:

位置和动量空间中量子系统概率密度的熵矩不仅描述了系统的一些基本和/或实验上可获得的量,而且还描述了雷尼型的熵不确定性度量,它允许人们找到位置-动量海森堡不确定原理的最相关的数学形式,即熵不确定关系。已知困难的三维问题的解可以通过在具有非标准维数$D$的类似系统中的$1/D$中的级数展开来非常好地近似;此外,本发明还许多原子和分子系统的几个物理量已经在数值上显示为具有大$D$极限中的值,其与由三维数值自洽场方法提供的相应值相当。$D$维类氢原子是多维多电子系统物理的主要原型。本文严格确定了$D$维类氢原子在大$D$极限下的Rényi熵的首项.作为一个副产品,我们表明,我们的结果饱和已知的位置动量雷尼熵为基础的不确定性关系。

英文摘要:

The entropic moments of the probability density of a quantum system in position and momentum spaces describe not only some fundamental and/or experimentally accessible quantities of the system, but also the entropic uncertainty measures of Rényi type which allow one to find the most relevant mathematical formalizations of the position-momentum Heisenberg's uncertainty principle, the entropic uncertainty relations. It is known that the solution of difficult three-dimensional problems can be very well approximated by a series development in $1/D$ in similar systems with a non-standard dimensionality $D$; moreover, several physical quantities of numerous atomic and molecular systems have been numerically shown to have values in the large-$D$ limit comparable to the corresponding ones provided by the three-dimensional numerical self-consistent field methods. The $D$-dimensional hydrogenic atom is the main prototype of the physics of multidimensional many-electron systems. In this work we rigorously determine the leading term of the Rényi entropies of the $D$-dimensional hydrogenic atom at the limit of large $D$. As a byproduct, we show that our results saturate the known position-momentum Rényi-entropy-based uncertainty relations.
