朗道能级在常数符号扰动下的命运
The Fate of the Landau Levels under Perturbations of Constant Sign
摘要:
我们发现,如果我们扰动的二维薛定谔算子与恒定磁场,由固定符号的有界电势的朗道能级不再是本征值。我们还表明,如果扰动不是固定的符号,那么任何朗道水平可能是一个任意大的,有限或无限,扰动问题的多重性的特征值。
英文摘要:
We show that the Landau levels cease to be eigenvalues if we perturb the 2D Schrödinger operator with constant magnetic field, by bounded electric potentials of fixed sign. We also show that, if the perturbation is not of fixed sign, then any Landau level may be an eigenvalue of arbitrary large, finite or infinite, multiplicity of the perturbed problem.
