摘要/Abstract

摘要：

该文采用Holstein Primakoff变换、双子格模型、相干态表示、含时微扰原理和多重尺度方法，研究了具有Aharonov Bohm磁通时，一维反铁磁链中的孤立子激发问题，探讨了Aharonov Bohm磁通对孤立子产生的效应，结果表明Aharonov Bohm磁通对孤立子的峰值、宽度、能量和自旋空间排列等均产生影响。

Abstract:

Employing Holstein Primakoff transformation, the double sublattice, the cohere nt state ansatz, and the time dependent variational principle and the me tho d of multiple scales,the authors have studied the effects of the Aharonov Bohm flux on the soliton in one dimensional antiferromagnetic chain. The results show tha t t he Aharonov Bohm flux have an effect on the peak, the width,the energy and the spatial configuration of the spin of the soliton.

Key words: AB flux, Antiferromagnetic chain;Soliton
