Effective quantum tunneling from semiclassical momentous approach

L. Aragon-Muñoz, G. Chacon-Acosta, H. Hernandez-Hernandez

摘要:

本文采用半经典的量子力学公式,以组态变量和量子色散的期望值为动力学变量,研究了势垒中的量子隧道效应。系统的演化是根据一个动力系统给出的,我们能够确定单个粒子的有效轨迹,这与量子力学的玻姆描述完全相似。我们得到了一种半经典约束的粒子以类似的方式与量子势,也确定了半经典的透射系数的隧穿过程。

英文摘要:

We study the quantum tunnel effect through a potential barrier employing a semiclassical formulation of quantum mechanics based on expectation values of configuration variables and quantum dispersions as dynamical variables. The evolution of the system is given in terms of a dynamical system for which we are able to determine effective trajectories for individual particles, in a total resemblance of the Bohmian description of quantum mechanics. We obtain a type of semiclassical confinement for particles in a similar way as with the quantum potential, and also determine a semiclassical transmission coefficient for the tunneling process.
