周期薛定谔算子缓变扰动的特征值

On the eigenvalues for slowly varying perturbations of a periodic Schrödinger operator

Magali Marx

摘要:

在本文中,我考虑一维周期薛定谔算子扰动的缓慢衰减的潜力。在绝热极限下,给出了周期算子在间隙中本征值的渐近展开式。当沿着周期势滑动微扰时,这些本征值振荡。我计算出振荡的指数小振幅。

英文摘要:

In this paper, I consider one-dimensional periodic Schr{ö}dinger operators perturbed by a slowly decaying potential. In the adiabatic limit, I give an asymptotic expansion of the eigenvalues in the gaps of the periodic operator. When one slides the perturbation along the periodic potential, these eigenvalues oscillate. I compute the exponentially small amplitude of the oscillations.
