双线性薛定谔方程的半全局弱镇定

Semi-global weak stabilization of bilinear Schrödinger equations

Karine Beauchard, Vahagn Nersesyan

摘要:

我们考虑一个线性薛定谔方程,在一个有界区域上,双线性控制,代表一个量子粒子在一个电场(控制)。最近,Nersesyan提出了显式反馈律,并证明了存在一个时间序列$(t_n)_{n \in \mathbb{N}}$,使闭环系统的解的值在$H^2$中弱收敛到基态。在这里,我们证明了整个解决方案的收敛性,作为$t \rightarrow + \infty$。证明依赖于控制李雅普诺夫函数和适应的拉萨尔不变原理偏微分方程。

英文摘要:

We consider a linear Schrödinger equation, on a bounded domain, with bilinear control, representing a quantum particle in an electric field (the control). Recently, Nersesyan proposed explicit feedback laws and proved the existence of a sequence of times $(t_n)_{n \in \mathbb{N}}$ for which the values of the solution of the closed loop system converge weakly in $H^2$ to the ground state. Here, we prove the convergence of the whole solution, as $t \rightarrow + \infty$. The proof relies on control Lyapunov functions and an adaptation of the LaSalle invariance principle to PDEs.
