强退化磁场下二维Schr dinger算子的Sharp谱渐近性

Sharp Spectral Asymptotics for two-dimensional Schrödinger operator with a strong degenerating magnetic field

Victor Ivrii

摘要:

本文考虑了具有简并磁场的二维薛定谔算子,在一般情况下,导出了谱渐近式$h\to +0$和$μ\to +\infty$,其中$h$和$μ$分别是普朗克参数和耦合参数。余数估计值为$O(μ^{-{\frac 1 2}}h^{-1})$,其介于磁场非简并时有效的$O(μ^{-1}h^{-1})$和磁场为0时有效的$O(h^{-1})$之间。由于$μ$接近其最大合理值$O(h^{-2})$,因此主部包含与相应经典动力学的短周期轨迹相关联的校正项。

英文摘要:

I consider two-dimensional Schrödinger operator with degenerating magnetic field and in the generic situation I derive spectral asymptotics as $h\to +0$ and $μ\to +\infty$ where $h$ and $μ$ are Planck and coupling parameters respectively. The remainder estimate is $O(μ^{-{\frac 1 2}}h^{-1})$ which is between $O(μ^{-1}h^{-1})$ valid as magnetic field non-degenerates and $O(h^{-1})$ valid as magnetic field is identically 0. As $μ$ is close to its maximal reasonable value $O(h^{-2})$ the principal part contains correction terms associated with short periodic trajectories of the corresponding classical dynamics.
