半经典动力学与磁Weyl演算

Semiclassical Dynamics and Magnetic Weyl Calculus

Max Lein

摘要:

外尔量子化和相关的半经典技术可以用来研究晶体固体在缓慢变化的外部电磁场作用下的导电性质。外部磁场是恒定的情况下,是不包括现有的理论作为证据,涉及通常的外尔演算崩溃。这就是所谓的量子霍尔效应,其中观察到横向电导的量子化。为了严格推导出半经典运动方程,需要系统地发展包含半经典参数的磁外尔演算。在数学上,参与分析的算子是磁伪微分算子,这本身就是数学和数学物理界感兴趣的话题。因此,我们将专门增加两章来进一步了解这些运营商的性质。

英文摘要:

Weyl quantization and related semiclassical techniques can be used to study conduction properties of crystalline solids subjected to slowly-varying, external electromagnetic fields. The case where the external magnetic field is constant, is not covered by existing theory as proofs involving usual Weyl calculus break down. This is the regime of the so-called quantum Hall effect where quantization of transverse conductance is observed. To rigorously derive semiclassical equations of motion, one needs to systematically develop a magnetic Weyl calculus which contains a semiclassical parameter. Mathematically, the operators involved in the analysis are magnetic pseudodifferential operators, a topic which by itself is of interest for the mathematics and mathematical physics community alike. Hence, we will devote two additional chapters to further understanding of properties of those operators.
