指数衰减的高阶伽莫夫态
Higher Order Gamow States with Exponential Decay
摘要:
我们从S-矩阵极点的更高的多重性类似的伽莫夫矢量描述共振从一阶极点。有了这些向量,我们构建了一个密度算子,它描述了与服从指数衰减律的高阶极点相关的共振。结果表明,由这些高阶伽莫夫向量构成的算子具有唯一的结构。
英文摘要:
We derive Gamow vectors from S-matrix poles of higher multiplicity in analogy to the Gamow vectors describing resonances from first-order poles. With these vectors we construct a density operator that describes resonances associated with higher order poles that obey an exponential decay law. It turns out that this operator formed by these higher order Gamow vectors has a unique structure.
