Study of a quantum scattering process by means of entropic measures
摘要：
在这项工作中，量子粒子通过势垒的散射过程被认为是。计算了该问题的统计复杂度和Fisher-Shannon信息。这些熵信息措施的行为作为入射粒子的能量的函数进行比较的行为的物理量，在障碍的反射系数。我们发现，这些统计幅度目前在反射系数为零的相同的情况下，它们的最小值。这些是实现通过势垒的总透射的情况，{ \it透明点}，这是由于系统的量子性质引起的典型现象。
英文摘要：
In this work, a scattering process of quantum particles through a potential barrier is considered. The statistical complexity and the Fisher-Shannon information are calculated for this problem. The behaviour of these entropy-information measures as a function of the energy of the incident particles is compared with the behaviour of a physical magnitude, the reflection coefficient in the barrier. We find that these statistical magnitudes present their minimum values in the same situations in which the reflection coefficient is null. These are the situations where the total transmission through the barrier is achieved, {\it the transparency points}, a typical phenomenon due to the quantum nature of the system.
