作为电子结构计算基础的大系统波函数

Wavefunctions for large systems as basis for electronic structure calculations

Peter Fulde

摘要:

基于多电子波函数的固体电子结构计算一直受到这样一种论点的阻碍,即对于大电子数的波函数不是一个合理的科学概念,因为它们面临指数壁问题。我们表明,这个问题可以避免使用累积量技术在制定波函数。因此,基于多电子函数的固体计算是可能的和有用的。这也包括具有强关联电子的系统。

英文摘要:

Electronic structure calculations for solids based on many-electron wavefunctions have been hampered by the argument that for large electron numbers wavefunctions are not a legitimate scientific concept, because they face an exponential wall problem. We show that this problem can be avoided by using cumulant techniques in formulating wavefunctions. Therefore calculations for solids based on many-electron functions are possible and useful. This includes also systems with strongly correlated electrons.
