电荷密度响应函数、交换空穴和定域轨道之间的关系

Relationships between charge density response functions, exchange holes and localized orbitals

Bastien Mussard, János G. Ángyán

摘要:

电荷密度响应函数和交换空穴通过物理学的基本涨落耗散定理紧密联系在一起。一个简单的近似模型的静态响应函数进行了直观的比较,在几个例子中,以证明这种关系。这项研究是通过说明著名的同构之间的交换孔和占主导地位的本地化轨道的平方位于交换孔函数的参考点的空间区域。讨论了这些关系对解释常见化学概念(例如离域)的影响。

英文摘要:

The charge density response function and the exchange hole are closely related to each other via the fundamental fluctuation-dissipation theorem of physics. A simple approximate model of the static response function is visually compared on several examples in order to demonstrate this relationship. This study is completed by illustrating the well-known isomorphism between the exchange hole and the square of the dominant localized orbital lying in the space region of the reference point of the exchange hole function. The implications of these relationships for the interpretation of common chemical concepts, such as delocalization, are discussed.
