用Lanczos方法计算出具有次近邻相互作用的一维量子链的基态和低激发态的能量,求出了模型的反常标度和归一化常数,并建立该模型的共形场理论。The energies of the ground state and the lowest-excited states of the one-dime-nsional NNN interaction quantum chain are calculated by using Lanczos method. The a no=nalous dimensions and normalizing constant are given from conformal field theory.
