In this work, we investigate the Shannon entropy of four recently proposed hyperbolic potentials through studying position and momentum entropies. Our analysis reveals that the wave functions of the single-well potentials U0,3 exhibit greater localization compared to the double-well potentials U1,2. This difference in localization arises from the depths of the single- and double-well potentials. Specifically, we observe that the position entropy density shows higher localization for the single-well potentials, while their momentum probability density becomes more delocalized. Conversely, the double-well potentials demonstrate the opposite behavior, with position entropy density being less localized and momentum probability density showing increased localization. Notably, our study also involves examining the Bialynicki-Birula and Mycielski (BBM) inequality, where we find that the Shannon entropies still satisfy this inequality for varying depths u¯. An intriguing observation is that the sum of position and momentum entropies increases with the variable u¯ for potentials U1,2,3, while for U0, the sum decreases with u¯. Additionally, the sum of the cases U0 and U3 almost remains constant within the relative value 0.01 as u¯ increases. Our study provides valuable insights into the Shannon entropy behavior for these hyperbolic potentials, shedding light on their localization characteristics and their relation to the potential depths. Finally, we extend our analysis to the Fisher entropy F¯x and find that it increases with the depth u¯ of the potential wells but F¯p decreases with the depth.
在这项工作中,我们通过研究位置熵和动量熵来研究最近提出的四种双曲势的香农熵。我们的分析表明,与双阱势U1,2相比,单阱势U0,3的波函数表现出更大的局域化。这种局域化的差异源于单阱势和双阱势的深度。具体而言,我们观察到单阱势的位置熵密度表现出更高的局域化,而它们的动量概率密度变得更加离域。相反,双阱势表现出相反的行为,位置熵密度局域化程度较低,动量概率密度局域化程度增加。值得注意的是,我们的研究还涉及检验比亚林斯基 - 比鲁拉和米乔尔斯基(BBM)不等式,我们发现对于不同的深度u¯,香农熵仍然满足该不等式。一个有趣的观察结果是,对于势U1,2,3,位置熵和动量熵的总和随变量u¯增加,而对于U0,总和随u¯减小。此外,随着u¯增加,U0和U3情况的总和在相对值0.01内几乎保持不变。我们的研究为这些双曲势的香农熵行为提供了有价值的见解,揭示了它们的局域化特征以及它们与势深度的关系。最后,我们将分析扩展到费希尔熵F¯x,发现它随势阱深度u¯增加,但F¯p随深度减小。
