用区域的慢变形控制薛定谔方程

Control of the Schrödinger equation by slow deformations of the domain

Alessandro Duca, Romain Joly, Dmitry Turaev

摘要:

研究了具有Dirichlet边界条件的薛定谔方程\begin{equation}\label{eq_abstract} i\partial_t u(t)=-Δu(t)~~~~~\text{ on }Ω(t) \tag{$\ast$} \end{equation}的能控性,其中$Ω(t)\subset\mathbb{R}^N$是一个时变区域.通过绝热变形$Ω(t)\subset\mathbb{R}$($t\in[0,T]$)证明了$L^2(Ω)$中\eqref{eq_abstract}的全局逼近能控性,使得$Ω(0)=Ω(T)=Ω$ .该控制强烈地基于由[18]提供的\eqref{eq_abstract}的哈密顿结构,其使得能够使用绝热运动。我们还讨论了几个明确的有趣的控制,我们在特定的框架中执行矩形域。

英文摘要:

The aim of this work is to study the controllability of the Schrödinger equation \begin{equation}\label{eq_abstract} i\partial_t u(t)=-Δu(t)~~~~~\text{ on }Ω(t) \tag{$\ast$} \end{equation} with Dirichlet boundary conditions, where $Ω(t)\subset\mathbb{R}^N$ is a time-varying domain. We prove the global approximate controllability of \eqref{eq_abstract} in $L^2(Ω)$, via an adiabatic deformation $Ω(t)\subset\mathbb{R}$ ($t\in[0,T]$) such that $Ω(0)=Ω(T)=Ω$. This control is strongly based on the Hamiltonian structure of \eqref{eq_abstract} provided by [18], which enables the use of adiabatic motions. We also discuss several explicit interesting controls that we perform in the specific framework of rectangular domains.
