禁带中薛定谔本征函数的节点集

Nodal sets of Schrödinger eigenfunctions in forbidden regions

Yaiza Canzani, John Toth

摘要:

本文研究作用在无边界紧致光滑黎曼流形上的半经典薛定谔算子的本征函数的节点集。我们证明了如果H是一个位于经典禁戒区域内的分离超曲面,则H不能作为无穷多个本征函数的零集的一个分量持续存在。此外,在真正的解析曲面,我们得到尖锐的上界的薛定谔本征函数的零集的交叉点的数量与一个固定的曲线,位于经典的禁区内。

英文摘要:

This note concerns the nodal sets of eigenfunctions of semiclassical Schrödinger operators acting on compact, smooth, Riemannian manifolds, with no boundary. We prove that if H is a separating hypersurface that lies inside the classically forbidden region, then H cannot persist as a component of the zero set of infinitely many eigenfunctions. In addition, on real analytic surfaces, we obtain sharp upper bounds for the number of intersections of the zero sets of the Schrödinger eigenfunctions with a fixed curve that lies inside the classically forbidden region.
