对称双势垒的共振

Resonances for symmetric two-barrier potentials

Francisco M. Fernández

摘要:

我们描述了一种精确计算一维势的束缚态和共振能的方法。我们计算了对称双势垒势的形状共振,并与Siegert近似、复标度法和盒稳定化方法的结果进行了比较。Breit-Wigner轮廓和其最大值附近的透射系数的比较表明,共振越尖锐,一致性越好。

英文摘要:

We describe a method for the accurate calculation of bound-state and resonance energies for one-dimensional potentials. We calculate the shape resonances for symmetric two-barrier potentials and compare them with those coming from the Siegert approximation, the complex scaling method and the box-stabilization method. A comparison of the Breit-Wigner profile and the transmission coefficient about its maximum illustrates that the agreement is better the sharper the resonance.
