摘要翻译：
我们考虑了具有近邻相互作用的一维横向Ising模型，精确地计算了一类激发态的纵向自旋-自旋关联。这些态在一维横向伊辛模型的扰动处理中起着重要的作用。对于关联的计算，我们遵循了Wu先前的步骤，使用Szego定理和Fisher-Hartwig猜想。结果表明，相关随距离($n$)的代数衰减为$1/\surdn$，并且根据横向场的大小，相关是振荡的或非振荡的。

英文摘要：
  We consider the transverse Ising model in one dimension with nearest-neighbour interaction and calculate exactly the longitudinal spin-spin correlation for a class of excited states. These states are known to play an important role in the perturbative treatment of one-dimensional transverse Ising model with frustrated second-neighbour interaction. To calculate the correlation, we follow the earlier procedure of Wu, use Szego's theorem and also use Fisher-Hartwig conjecture. The result is that the correlation decays algebraically with distance ($n$) as $1/\surd n$ and is oscillatory or non-oscillatory depending on the magnitude of the transverse field.
