论文摘要
本章从其可观察到的电磁反应的角度描述了拓扑（狄拉克和Weyl）半学。我们认为，这种响应可以用拓扑术语表示，并与非量化（非整体）系数表示，并与Luttinger的定理建立联系，该定理将普通金属的费米表面的大小与每个单位电池的电子数量相关联。我们讨论与这种拓扑响应有关的可观察到的运输现象。
This chapter describes topological (Dirac and Weyl) semimetals from the viewpoint of their observable electromagnetic response. We argue that this response may be represented by topological terms with unquantized (non-integer) coefficients and make a connection with the Luttinger's theorem, which relates the size of the Fermi surface of an ordinary metal to the number of electrons per unit cell. We discuss observable transport phenomena, associated with this topological response.
