Matthias Baur, Timo Weidl

AI总结:

本文研究强磁场下磁 Dirichlet Laplacian 的特征值渐近行为,证明圆盘上特征值分支的线性渐近及指数小余项,并揭示强场会以与区域无关的尖锐因子违背 Pólya 谱界。

摘要:

我们考虑有限测度区域上具有恒定磁场的磁 Dirichlet Laplacian。首先,在圆盘情形下,我们证明:当磁场强度趋于无穷大时,关于磁场强度的特征值分支表现为渐近线性,并带有一个指数小的余项;我们计算了该余项的渐近表达式。其次,我们表明,对于足够大的磁场强度,对应于非磁 Dirichlet Laplacian 的 Pólya 猜想的谱界被违背,其超出因子是尖锐的,并且与区域无关。

英文摘要:

We consider the magnetic Dirichlet Laplacian with constant magnetic field on domains of finite measure. First, in the case of a disk, we prove that the eigenvalue branches with respect to the field strength behave asymptotically linear with an exponentially small remainder term as the field strength goes to infinity. We compute the asymptotic expression for this remainder term. Second, we show that for sufficiently large magnetic field strengths, the spectral bound corresponding to the Pólya conjecture for the non-magnetic Dirichlet Laplacian is violated up to a sharp excess factor which is independent of the domain.
