摘要

太赫兹涡旋光束描述的光是比普通的总角动量大。增加的总角动量改变了光学选择规则，开辟了材料研究的新领域。我们讨论了涡旋光束的基本概念和未来太赫兹研究的可能途径。以朗道能级跃迁的实验为例。

THz Vortex Light and Landau Level Transitions in Topological Semimetals

A THz vortex beam describes light with a larger than ordinary total angular momentum. Increased total angular momentum modifies the optical selection rules, opening a new territory of material research. We discuss the basic concept of vortex beams and a possible approach for future THz studies. The experiments on Landau level transitions will be given as an example.
