二维快速振荡薛定谔算子的束缚态

Bound states for rapidly oscillatory Schrödinger operators in dimension 2

Alexis Drouot

摘要:

研究了具有快速振荡势$V(x) = W(x,x/\varepsilon)$的$\mathbb{R}^2$上薛定谔算子的本征值,其中$W(x,y) \in C^\infty_0(\mathbb{R}^2 \times \mathbb{T}^2)$满足$\int_{\mathbb{T}^2} W(x,y) dy =0$ .我们证明了对于足够小的$\varepsilon$,这样的运营商有一个唯一的负本征值,这是指数接近$0$。

英文摘要:

We study the eigenvalues of Schrödinger operators on $\mathbb{R}^2$ with rapidly oscillatory potential $V(x) = W(x,x/\varepsilon)$, where $W(x,y) \in C^\infty_0(\mathbb{R}^2 \times \mathbb{T}^2)$ satisfies $\int_{\mathbb{T}^2} W(x,y) dy =0$. We show that for $\varepsilon$ small enough, such operators have a unique negative eigenvalue, that is exponentially close to $0$.
