双量子阱电子系统中相互作用引起的朗道能级合并
Interaction-induced merging of Landau levels in an electron system of double quantum wells
摘要：
我们证明了在固定整数填充因子的垂直磁场作用下，双量子阱中的化学势跳跃消失是由相互作用引起的能级合并引起的.在合并制度的分布函数是特殊的，在找到一个电子的能量等于化学势的概率是不同的两个合并的水平。
英文摘要：
We show that the disappearance of the chemical potential jumps over the range of perpendicular magnetic fields at fixed integer filling factor in a double quantum well with a tunnel barrier is caused by the interaction-induced level merging. The distribution function in the merging regime is special in that the probability to find an electron with energy equal to the chemical potential is different for the two merged levels.
