超对称量子力学中的等效厄米算符

Equivalent Hermitian operator from supersymmetric quantum mechanics

Boris F. Samsonov, V. V. Shamshutdinova, A. V. Osipov

摘要:

具有实谱和离散谱的可对角化的伪厄米哈密顿算子是厄米哈密顿算子的超伴子,它们必须是具有厄米正定非奇异$η$算子的$η$ -伪厄米算子。我们表明,尽管事实上,一个$η$运营商产生的超对称变换,对应于精确的超对称,是奇异的,它可以用来找到一个厄米特运营商的本征函数等价于给定的伪厄米特哈密顿量。一旦找到厄米特算子的本征函数,就可以借助于谱分解来重构该算子。

英文摘要:

Diagonalizable pseudo-Hermitian Hamiltonians with real and discrete spectra, which are superpartners of Hermitian Hamiltonians, must be $η$-pseudo-Hermitian with Hermitian, positive-definite and non-singular $η$ operators. We show that despite the fact that an $η$ operator produced by a supersymmetric transformation, corresponding to the exact supersymmetry, is singular, it can be used to find the eigenfunctions of a Hermitian operator equivalent to the given pseudo-Hermitian Hamiltonian. Once the eigenfunctions of the Hermitian operator are found the operator may be reconstructed with the help of the spectral decomposition.
