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。

As we know, if one mode of the electromagnetic field is prepared in a squeezed state, the quantum fluctuation of one of its quadrature components can be lower than that of the corresponding part in a coherent state and that of the other is higher, and we can tune the signal-to-noise ratios of its quadrature components: one of the quadratures can be used to absorb the quantum-mechanical noise, while the other one serves to transmit an extremely well-defined signal.

由于压缩态中光场某一分量的量子涨落可以小于相干态中的量子涨落，即可以小于量子涨落的最小值，因此可以用来改变信号传递的信噪比，从而在低噪声通讯、弱信号探测、高精密测量等方面具有重要的应用前景。

At the same time, we studied the influence of quantum interference on the squeezing spectrum of the resonance fluorescence emitted from a V-type three-level atom and a -type four-level atom which are driven by coherent fields. We showed that quantum interference can greatly enhance squeezing in the components of phase quadratures at atomic frequency and change the squeezing spectrum .
