| Abstract: | 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. |
