LetH= - Δ+V+Fx1 withV(x1,x⊥)在第一个变量中是解析的,V(x1+ia, x⊥)是有界的,对于每个∈x, asx→∞递减到零。设ψ是负特征值的- Δ+V的特征向量。在我们的结果中,我们证明了f≠0时,(ψ,e−Hψ)以由h的共振位置决定的指数速率衰减。这种指数衰减与以幂律衰减为规则的“传统”原子共振形成鲜明对比。
LetH=−Δ+V+Fx1 withV(x1,x⊥) analytic in the first variable andV(x1+ia, x⊥) bounded and decreasing to zero asx → ∞ for eacha ∈ ℝ. Let ψ be an eigenvector of −Δ+V with negative eigenvalue. Among our results we show that forF≠0, (ψ,e−Hψ) decays exponentially at a rate governed by the positions of the resonances ofH. This exponential decay is in marked contrast to “conventional” atomic resonances for which power law decay is the rule.
