多态薛定谔算符的散射理论

Scattering theory for multistate Schrödinger operators

Sohei Ashida

摘要:

我们研究了与分子动力学有关的多态薛定谔算符。我们认为,不一定衰减的潜力,并证明没有奇异的连续谱和传播的估计,这意味着散射速度大于一个正常数和衰减的状态与潜在的高于考虑在无穷大的能量。我们还考虑了具有多体结构的多态薛定谔算符。我们得到了多体算子的最小速度估计和最小速度估计。速度的下限由能量和低于能量的阈值之间的距离确定。

英文摘要:

We study multistate Schrödinger operators related to molecular dynamics. We consider potentials which do not necessarily decay and prove absence of the singular continuous spectrum and propagation estimates which mean the scattering at speed larger than a positive constant and decay of the state with potentials higher than considered energy at infinity. We also consider the multistate Schrödinger operators with many-body structures. We obtain the Mourre estimate and the minimal velocity estimate for the many-body operators. The lower bound of the velocity is determined by the distance between the energy and thresholds below the energy.
