Nodal gap of the failed Kondo insulator CeRu4Sn6

Kondo insulators and in particular their non-cubic representatives have remained poorly understood. Recent optical spectroscopy measurements together with calculations within...近藤绝缘体（Kondo insulators），尤其是其非立方构型的代表性材料，迄今仍未得到充分的研究与认知。近期的光学光谱学测量结合相关理论计算……
