论文摘要
我们通过潜在的屏障研究量子隧道的效应,该效应采用了基于构型变量的期望值和量子分散剂作为动力学变量的量子力学的半经典公式。该系统的演变是根据动力学系统给出的,我们能够确定单个颗粒的有效轨迹,这是Bohmian对量子力学的描述的完全相似之处。我们以与量子电位相似的方式获得了颗粒的半经典限制,还确定了隧穿过程的半经典传输系数。
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.
