非厄米一维哈密顿算子的谱奇异性:恒等式的解

Spectral singularities for Non-Hermitian one-dimensional Hamiltonians: puzzles with resolution of identity

A. A. Andrianov, F. Cannata, A. V. Sokolov

摘要:

我们研究了具有谱奇异性的非厄米特哈密顿算子的本征函数的双正交集的完备性。构造了δ型势和光滑势的恒等式的正确分解。它们的形式和贡献的光谱奇异性取决于类的功能采用的物理状态。有了这个规范,就不存在源于谱奇点的对完整性的阻碍。

英文摘要:

We examine the completeness of bi-orthogonal sets of eigenfunctions for non-Hermitian Hamiltonians possessing a spectral singularity. The correct resolutions of identity are constructed for delta like and smooth potentials. Their form and the contribution of a spectral singularity depend on the class of functions employed for physical states. With this specification there is no obstruction to completeness originating from a spectral singularity.
