F. Cannata, M. V. Ioffe, D. N. Nishnianidze

摘要:

研究了一类具有特定形式复势的二维量子模型。它们可以被认为是最近研究的具有二次相互作用的模型的推广,不适合传统的变量分离。在本例中,形状不变性的性质提供了频谱的等距形式和解析构造本征函数的算法。证明了该哈密顿量是不可对角化的,并且恒等式的分解也必须包含相应的关联函数。在二阶加四阶非简谐相互作用的特殊情况下,给出了最低能级的波函数及其相关函数的表达式,并给出了产生高阶波函数的递推算法.

英文摘要:

We study a class of quantum two-dimensional models with complex potentials of specific form. They can be considered as the generalization of a recently studied model with quadratic interaction not amenable to conventional separation of variables. In the present case, the property of shape invariance provides the equidistant form of the spectrum and the algorithm to construct eigenfunctions analytically. It is shown that the Hamiltonian is non-diagonalizable, and the resolution of identity must include also the corresponding associated functions. In the specific case of anharmonic second-plus-fourth order interaction, expressions for the wave functions and associated functions are constructed explicitly for the lowest levels, and the recursive algorithm to produce higher level wave functions is given.
