一维Dirac方程的Poincare映射解

Solution of One-dimensional Dirac Equation via Poincare Map

Hocine Bahlouli, El Bouazzaoui Choubabi, Ahmed Jellal

摘要:

我们解决了一般的一维狄拉克方程使用的“庞加莱映射”的方法,避免了任何近似的空间导数,并减少了一个简单的递归关系,这是非常实用的数值实现的角度来看,问题。为了测试这种方法的效率和快速收敛性,我们将其应用到矢量耦合Woods-Saxon势,这是完全可解的。与现有的分析结果的比较是令人印象深刻的,因此验证了该方法的准确性和效率。

英文摘要:

We solve the general one-dimensional Dirac equation using a "Poincare Map" approach which avoids any approximation to the spacial derivatives and reduces the problem to a simple recursive relation which is very practical from the numerical implementation point of view. To test the efficiency and rapid convergence of this approach we apply it to a vector coupling Woods--Saxon potential, which is exactly solvable. Comparison with available analytical results is impressive and hence validates the accuracy and efficiency of this method.
