In this work, we study the quantum information entropies for two different types of hyperbolic single potential wells. We first study the behaviors of the moving particle subject to two different hyperbolic potential wells through focusing on their wave functions. The shapes of these hyperbolic potentials are similar, but we notice that their momentum entropy densities change along with the width of each potential and the magnitude of position entropy density decreases when the momentum entropy magnitude increases. On the other hand, we illustrate the behaviors of their position and momentum entropy densities. Finally, we show the variation of position and momentum entropies Sx and Sp with the change of the potential well depth and verify that their sum still satisfies the BBM inequality relation.
在这项工作中,我们研究了两种不同类型双曲单势阱的量子信息熵。我们首先通过关注其波函数来研究受两种不同双曲势阱作用的运动粒子的行为。这些双曲势的形状相似,但我们注意到它们的动量熵密度随每个势的宽度而变化,并且当动量熵大小增加时,位置熵密度的大小会减小。另一方面,我们阐述了它们的位置和动量熵密度的行为。最后,我们展示了位置熵 (S_x) 和动量熵 (S_p) 随势阱深度变化的情况,并验证它们的和仍然满足BBM不等式关系。
