论文摘要
我们研究波函数（DE）定位与四极台球中避免穿越之间的关系。我们采用反向参与率，Renyi熵和根平方（RMS）图像对比度作为波函数（DE）定位的三种类型的措施。发现所有这些措施的行为都相似，在避免过境的中心表现出最小值，其中波函数被最大地定位。我们的结果表明，尽管RMS的对比度在其中最敏感的措施中，但这些数量可能是波函数定位（DE）定位的良好指标。
We study the relation between wavefunction (de)localization and the avoided crossing in a quadrupole billiard. We employ the inverse participation ratio, the Renyi entropy and the root-mean-square (rms) image contrast as the three types of measures for wavefunction (de)localization. It is found that all these measures behave similarly, exhibiting a minimum at the center of avoided crossing, where wavefunction is maximally delocalized. Our results show that these quantities can be good indicators for wavefunction (de)localization although the rms contrast yields the most sensitive measure among them.
