关于两阶Aharonov-Bohm效应的Pauli算子

On the Pauli operator for the Aharonov-Bohm effect with two solenoids

V. A. Geyler, P. Stovicek

摘要:

本文考虑自旋为1/2的带电粒子在两个理想Aharonov-Bohm通量作用下的平面运动。我们表明,泡利算子作为一个微分算子是由适当的边界条件定义在两个涡。此外,我们明确地构建了一个基础的对称算子的不足子空间,通过限制域的功能与支持分离的旋涡。这种构造使得将克莱因公式应用于泡利算子成为可能。

英文摘要:

We consider a spin-1/2 charged particle in the plane under the influence of two idealized Aharonov-Bohm fluxes. We show that the Pauli operator as a differential operator is defined by appropriate boundary conditions at the two vortices. Further we explicitly construct a basis in the deficiency subspaces of the symmetric operator obtained by restricting the domain to functions with supports separated from the vortices. This construction makes it possible to apply the Krein's formula to the Pauli operator.
