计算机编制Young图技巧

THE TECHNIQUE TO MAKE YOUNG PATTERN WITH A COMPUTER CODE

一、引言多粒子空穴系统的能态密度中泡利不相容原理的效应最近才找到严格求解方法。证实了泡利原理在低激发态或多粒子空穴数的状态下起着相当重要的作用。能态密度中泡利原理修正项是用一套Young图表示,由于Young图的个数是随粒子数或空穴数加大而剧增,若在实际计算中用手写方式输入计算机势必把问题变得十分烦杂。本文通过Young图的性质,找出一套方法,解决了计算机自动编制Young图的途径。

The Young pattern in group theory is employed to study the Pauli principlecorrection of particle and hole state densities. The technique to produce the Youngpettern with computer code is developed. It makes theoretical calculations very conveniently.
