分子体系中密度矩阵的化学描述符、凸性和结构

Chemical descriptors, convexity and structure of density matrices in molecular systems

Roberto C. Bochicchio

摘要:

分子系统中的电子能量矩阵和密度矩阵关于粒子数是凸的。因此,基于其衍生物的化学描述符对孤立系表现出不连续性的阻碍,从而导致高阶衍生物不确定。物理域与环境之间的相互作用的引入诱导了巨正则公式中的密度矩阵的相干结构,抑制了导致描述符的正确定义的不连续性。

英文摘要:

The electron energy and density matrices in molecular systems are convex in respect of the number of particles. So that, the chemical descriptors based on their derivatives present the hamper of discontinuities for isolated systems and consequently higher order derivatives are undefined. The introduction of the interaction between the physical domain with an environment induces a coherent structure for the density matrix in the grand-canonical formulation suppressing the discontinuities leading to the proper definitions of the descriptors.
