一维Hulthén势中Dirac粒子的透射共振

Transmission resonances for a Dirac particle in a one-dimensional Hulthén potential

Jian You Guo, Shao Wei Jin, Fu Xin Xu

摘要:

我们精确地求解了空间一维Hulthén势下的二分量Dirac方程,并给出了散射态的Dirac旋量的超几何函数形式.利用波函数的匹配条件计算了反射系数和透射系数,并研究了透射共振的存在条件。此外,我们还证明了透射共振条件如何依赖于势的形状。

英文摘要:

We have solved exactly the two-component Dirac equation in the presence of a spatially one-dimensional Hulthén potential, and presented the Dirac spinors of scattering states in terms of hypergeometric functions. We have calculated the reflection and transmission coefficients by the matching conditions on the wavefunctions, and investigated the condition for the existence of transmission resonances. Furthermore, we have demonstrated how the transmission-resonance condition depends on the shape of the potential.
