电子相互作用和孤子元激发(Ⅱ)电子关联对孤子激发能的影响

ELECTRON ELECTRON INTERACTION AND SOLITON EXCITATION(Ⅱ) THE EFFECT OF ELECTRON CORRELATION ON THE CREATION ENERGY OF SOLITON

电子相互作用对孤子的激发能是增加还是减小，各种理论相互矛盾．分析了产生矛盾的原因，提出了计算孤子激发能的新方法，结果表明：电子相互作用使荷电孤子对的激发能增加。

Abstract Does electron interaction enhance or reduce the creation energy of soliton? The results based on different theories conflict with each other. In this paper, the reason for such conflict has been revealed and a new method is proposed to calculate the creation energy of soliton (only intensive quantities are involved in calculation). Our result shows: the electron interaction enhances the creation energy of soliton, but the enhancement of the soliton is less than that of e h pair.
