摘要:

本文针对多体磁薛定谔方程,证明了从正测度集合出发的唯连续延拓性质。该性质保证:若薛定谔方程的一个解在某个正测度集合上为零,则该解恒等于零。我们明确考虑了由单体或两体函数之和构成的势能,这类势能是多体量子力学中哈密顿量的典型形式。作为一个特殊情形,我们能够处理原子和分子哈密顿量。唯连续延拓性质在密度泛函理论中具有重要作用,这凸显了其在量子化学中的相关性。

英文摘要:

The unique-continuation property from sets of positive measure is here proven for the many-body magnetic Schrödinger equation. This property guarantees that if a solution of the Schrödinger equation vanishes on a set of positive measure, then it is identically zero. We explicitly consider potentials written as sums of either one-body or two-body functions, typical for Hamiltonians in many-body quantum mechanics. As a special case, we are able to treat atomic and molecular Hamiltonians. The unique-continuation property plays an important role in density-functional theories, which underpins its relevance in quantum chemistry.
