测度值磁场的Pauli算子和Aharonov-Casher定理

Pauli operator and Aharonov Casher theorem for measure valued magnetic fields

Laszlo Erdos, Vitali Vougalter

摘要:

我们定义了二维泡利算子,并确定其核心的磁场是定期的Borel措施。磁场是由标量势产生的,因此我们绕过了矢量势上通常的$\bA\in L^2_{loc}$条件,该条件不允许考虑这种奇异场。本文将Aharonov-Casher定理推广到磁场是有限全变差的情形,并给出了无限全变差情形下的一个反例。其中一个关键的技术工具是奇异积分算子的加权$L^2$估计。

英文摘要:

We define the two dimensional Pauli operator and identify its core for magnetic fields that are regular Borel measures. The magnetic field is generated by a scalar potential hence we bypass the usual $\bA\in L^2_{loc}$ condition on the vector potential which does not allow to consider such singular fields. We extend the Aharonov-Casher theorem for magnetic fields that are measures with finite total variation and we present a counterexample in case of infinite total variation. One of the key technical tools is a weighted $L^2$ estimate on a singular integral operator.
