N重超对称框架下的非线性赝超对称性

Nonlinear Pseudo-Supersymmetry in the Framework of N-fold Supersymmetry

Artemio Gonzalez-Lopez, Toshiaki Tanaka

摘要:

我们回顾了认识与PT对称量子理论有关的各种概念的不同数学性质的重要性。在阐明了超对称性与伪超对称性的关系之后,我们一般地证明了Sinha和Roy最近提出的非线性伪超对称性只是N重超对称性的一个特例.特别地,我们证明了这些作者所构造的所有模型都具有A型2重超对称性。此外,我们还证明了任意一个具有两个封闭形式的(局部)解的单体量子哈密顿量都属于A型2重超对称,而不管它是否是厄米特的、PT对称的、伪厄米特的等等.

英文摘要:

We recall the importance of recognizing the different mathematical nature of various concepts relating to PT-symmetric quantum theories. After clarifying the relation between supersymmetry and pseudo-supersymmetry, we prove generically that nonlinear pseudo-supersymmetry, recently proposed by Sinha and Roy, is just a special case of N-fold supersymmetry. In particular, we show that all the models constructed by these authors have type A 2-fold supersymmetry. Furthermore, we prove that an arbitrary one-body quantum Hamiltonian which admits two (local) solutions in closed form belongs to type A 2-fold supersymmetry, irrespective of whether or not it is Hermitian, PT-symmetric, pseudo-Hermitian, and so on.
