摘要
一个模型被建议与二学习量戒指深深地在一个可变磁场下面绑电子。强调被放到清澈尺寸(直径) 和部分 Aharonov-Bohm 摆动上的戒指的宽度的效果。尺寸的减小将在扎根的州的精力并且在坚持的电流导致很强壮的摆动，这被发现。电子关联被显示出波浪功能的节的结构也表明了。
A model is proposed to study the quantum rings with two deeply bound electrons under a variable magnetic field. The emphasis is placed to clarify the effect of the size （diameter） and the width of the ring on the fractional Aharonov-Bohm oscillation. It was found that the reduction of size will lead to a very strong oscillation in the ground state energy and in the persistent current. The electronic correlation has also been demonstrated by showing the nodal structures of wave functions.
