N重超对称框架下的两步形状不变性

Two-step Shape Invariance in the Framework of N-fold Supersymmetry

Barnana Roy, Toshiaki Tanaka

摘要:

在N重超对称框架下,我们广泛地研究了两步形状不变性。我们首先证明了任何两步形不变系统都具有带中间哈密顿量的A型2重超对称性,因而也具有二阶仿对称性。利用A型2重超对称的一般形式,系统地构造了两步形不变势。除了已知的普通形状不变势,我们得到了几个新的和新颖的两步形状不变的,不是普通的形状不变的。此外,后者的一些潜力是有条件的两步形状不变,因此是有条件可解的。

英文摘要:

We extensively investigate two-step shape invariance in the framework of N-fold supersymmetry. We first show that any two-step shape-invariant system possesses type A 2-fold supersymmetry with an intermediate Hamiltonian and thus has second-order parasupersymmetry as well. Employing the general form of type A 2-fold supersymmetry, we systematically construct two-step shape-invariant potentials. In addition to the well-known ordinary shape-invariant potentials, we obtain several new and novel two-step shape-invariant ones which are not ordinary shape invariant. Furthermore, some of the latter potentials are conditionally two-step shape invariant and thus are conditionally solvable.
