量子系统的信息论及其类氢应用

Information theory of quantum systems with some hydrogenic applications

J. S. Dehesa, D. Manzano, P. S. Sánchez-Moreno, R. J. Yáñez

摘要:

量子系统的信息论表示,它补充了熟悉的能量描述的密度泛函和波函数为基础的理论,在这里讨论。根据它,量子力学非相对论系统的内部无序可以通过薛定谔概率密度的各种单一(Fisher信息,香农熵)和复合(例如Cramer-Rao,LMC形状和Fisher-Shannon复杂性)泛函来量化。首先,我们研究这些概念及其在具有中心势的量子系统中的应用。然后,我们计算这些措施氢系统,强调其预测能力的各种物理现象。最后,指出了目前存在的一些问题。

英文摘要:

The information-theoretic representation of quantum systems, which complements the familiar energy description of the density-functional and wave-function-based theories, is here discussed. According to it, the internal disorder of the quantum-mechanical non-relativistic systems can be quantified by various single (Fisher information, Shannon entropy) and composite (e.g. Cramer-Rao, LMC shape and Fisher-Shannon complexity) functionals of the Schrödinger probability density. First, we examine these concepts and its application to quantum systems with central potentials. Then, we calculate these measures for hydrogenic systems, emphasizing their predictive power for various physical phenomena. Finally, some recent open problems are pointed out.
