密度泛函理论?答:密度泛函理论的含义从其英文“Density functional theory”更能直观的反映出来,它应用“电子密度泛函数”来处理多体问题。而泛函数通常指一种定义域为函数,而值域为实数的函数,换句话说,是一种函数组成的向量空间到实数的一个映射[3]。泛函数常用来寻找某个能量泛函的最小系统状态,这为密度泛函理论...

Tiny DFT is a minimalistic atomic Density Functional Theory (DFT) code, mainly for educational purposes. It only supports spherically symmetric atoms and local exchange-correlation functionals (at the moment only Dirac exchange). The code is designed with the following criteria in mind: It depends ...
