分数量子霍尔效应
Fractional quantum Hall effectA quantum mechanical phenomenon observed in two-dimensional electron systems subjected to low temperatures and strong magnetic fields, characterized by the quantization of the Hall conductance in fractional multiples of the elementary conductance quantum. / 一种在低温和强磁场下观察到的二维电子系统的量子力学现象，其霍尔电导率以基本电导量子分数的倍数进行量子化。
