Scarf II势的PT对称破缺和伪范数的显式表示
PT symmetry breaking and explicit expressions for the pseudo-norm in the Scarf II potential
摘要：
首次导出了PT对称势和Hermitian Scarf II势任意束缚态的伪范数、范数和正交关系的封闭表达式。伪范数一般具有不定号。分析了PT对称性自发击穿的某些方面。
英文摘要：
Closed expressions are derived for the pseudo-norm, norm and orthogonality relations for arbitrary bound states of the PT symmetric and the Hermitian Scarf II potential for the first time. The pseudo-norm is found to have indefinite sign in general. Some aspects of the spontaneous breakdown of PT symmetry are analysed.
