As to the higher Landau levels, we conducted systematically calculations for the various possible ground states, such as the Laughlin liquid, the composite fermion liquid, the Wigner crystal, and the charge density wave . We find that when the Landau level index N≥2, the fractional quantum Hall states are ruled out and the CDW and Wigner crystal dominate. An exception occurs at around v=4+1/6, where the composite fermion liquid may be more energetically preferable than the CDW and the Wigner crystal states. This result provides a new explanation to the so-called re-entrant integral quantum Hall effect. In fact, the feature of isotropically metallic property at this filling is discerned from the experiment.

对于高朗道能级，我们对各种可能的基态，比如量子霍耳态，复合费米子流体，Wigner晶体，电荷密度波等，做了系统的计算，我们发现，当朗道能级N≥2时，分数量子霍耳态不再出现，Wigner晶体和电荷密度波将占主导地位，一个例外就是在ν=4+1/6附近，复合费米子流体可能出现在从Wigner晶体到电荷密度波晶体之间，该结果为上述的重进入整数量子霍耳效应现象提出了一种新的解释。
