摘要
以一维序参量守恒的反铁磁链为例，采用双子格模型和相干态表示，分析了Ａｈａｒｏｎｏｖ－Ｂｏｈｍ磁通对一维反铁磁链中的孤子所产生的影响，结果表明Ａｈａｒｏｎｏｖ－Ｂｏｈｍ磁通对孤子的峰值、宽度、静止能量和有效质量均有影响。
Taking order parameter preserving antiferromagnet as an example, employing the double sublattice mode and the coherent state ansatz, we have studied the effects of the Aharonov Bohm flux on the soliton in a one dimensional antiferromagnet. The effects on the peak, the width, the rest energy and the effective mass of the soliton by the Aharonov Bohm flux are shown.
