带边界系统的自伴整体Hamilton算子

Self-adjoint, globally defined Hamiltonian operators for systems with boundaries

Nuno Costa Dias, Andrea Posilicano, Joao Nuno Prata

摘要:

对于Hilbert空间$L^2(\RE^d)$上的一般自伴Hamilton算子$H_0$,我们确定了$L^2(\RE^d)$上的所有自伴Hamilton算子$H$的集合,它们动态地将系统限制在开集$Ω\subset \RE^d$上,同时再现$ H_0$在适当的算子域上的作用.在$H_0=-Δ+V$的情况下,我们构造这些哈密顿量明确表明,他们可以写在形式$H=H_0+ B$,其中$B$是一个奇异的边界势和$H$是自共轭的最大域。本文还介绍了它在一维边界系统形变量子化中的应用。

英文摘要:

For a general self-adjoint Hamiltonian operator $H_0$ on the Hilbert space $L^2(\RE^d)$, we determine the set of all self-adjoint Hamiltonians $H$ on $L^2(\RE^d)$ that dynamically confine the system to an open set $Ω\subset \RE^d$ while reproducing the action of $ H_0$ on an appropriate operator domain. In the case $H_0=-Δ+V$ we construct these Hamiltonians explicitly showing that they can be written in the form $H=H_0+ B$, where $B$ is a singular boundary potential and $H$ is self-adjoint on its maximal domain. An application to the deformation quantization of one-dimensional systems with boundaries is also presented.
