AI 中文摘要
我们研究了由dressing链理论所启发的量子力学Kronig-Penney模型的谐振修正的谱性质。特别地,我们证明在特殊情形下,相应的基态可以显式给出,且所有谱隙具有相同长度,其端点表示为相应的Weber-Hermite函数的零点。
英文摘要
We study the spectral properties of the harmonic modification of the quantum mechanical Kronig-Penney model motivated by the theory of the dressing chain. In particular, we show that in the special cases the corresponding ground states can be given explicitly and all spectral gaps have the same length with the ends expressed as zeros of the corresponding Weber-Hermite functions.
