超对称双正交量子系统

Supersymmetric Biorthogonal Quantum Systems

Thomas Curtright, Luca Mezincescu, David Schuster

摘要:

我们讨论了超对称双正交系统,重点给出了PT对称模型的谱奇点处的周期解。对于这些周期解,对偶函数是服从非齐次方程的相关多项式。我们详细地构造了超对称势对V_{+/-}(z)= -U(z)^2 +/- z(d/(dz))U(z)的一些显式例子,其中U(z)= \sum_{k>0} u_{k} z^{k}.特别地,我们考虑由U(z)= z和z/(1-z)生成的情况。我们还简要地考虑了磁矢势对这些系统的配分函数的影响。

英文摘要:

We discuss supersymmetric biorthogonal systems, with emphasis given to the periodic solutions that occur at spectral singularities of PT symmetric models. For these periodic solutions, the dual functions are associated polynomials that obey inhomogeneous equations. We construct in detail some explicit examples for the supersymmetric pairs of potentials V_{+/-}(z) = -U(z)^2 +/- z(d/(dz))U(z) where U(z) = \sum_{k>0}u_{k}z^{k}. In particular, we consider the cases generated by U(z) = z and z/(1-z). We also briefly consider the effects of magnetic vector potentials on the partition functions of these systems.
