一维库仑问题

The one-dimensional Coulomb Problem

G. Abramovici, Y. Avishai

摘要:

本文研究了库仑势V(x)= λ/ |x|的一维散射,包括排斥(c>0)和吸引(c<0)两种情况.使用了两种正则化x=0处奇点的方法,得出了相同的结论,即透射为零。对于一个吸引势(c<0),我们发现了两组束缚态:第一组束缚态是由“规则”(Rydberg)束缚态组成的,遵循标准的正交关系;第二组由“反常”束缚态组成(在某种意义上有待澄清),它们总是作为相干态弛豫。

英文摘要:

One-dimensional scattering by a Coulomb potential V(x)=lambda/|x| is studied for both repulsive (c>0) and attractive (c<0) cases. Two methods of regularizing the singularity at x=0 are used, yielding the same conclusion, namely, that the transmission vanishes. For an attractive potential (c<0), two groups of bound states are found. The first one consists of "regular" (Rydberg) bound states, respecting standard orthogonality relations. The second set consists of "anomalous"} bound states (in a sense to be clarified), which always relax as coherent states.
