三维尖锥中的磁拉普拉斯算子

Magnetic Laplacian in sharp three dimensional cones

Virginie Bonnaillie-Noël, Monique Dauge, Nicolas Popoff, Nicolas Raymond

摘要:

本文的核心结果是在半空间中的锥上具有恒定磁场的磁拉普拉斯算子的基态能量的一个上界。这个界限涉及到一个加权范数的磁场有关的力矩上的一个平面部分的圆锥。当圆锥是尖的,即当它的截面很小时,上界趋于0。证明了尖锥族的本质谱的一个下界,这意味着如果截面足够小,基态能量是本征值。这种情况下产生的角落浓度在半经典极限为磁性薛定谔运营商时,这样的尖锐锥参与。

英文摘要:

The core result of this paper is an upper bound for the ground state energyof the magnetic Laplacian with constant magnetic field on cones that are contained in ahalf-space. This bound involves a weighted norm of the magnetic field related to momentson a plane section of the cone. When the cone is sharp, i.e. when its section is small, thisupper bound tends to 0. A lower bound on the essential spectrum is proved for familiesof sharp cones, implying that if the section is small enough the ground state energy is aneigenvalue. This circumstance produces corner concentration in the semi-classical limit forthe magnetic Schrödinger operator when such sharp cones are involved.
