摘要:

从理论上分析了外尔金属中反转对称性破缺对杂质分子态结构的影响。我们表明,对于一个高度非中心对称的外尔金属主机的情况下,交替成键和反键轨道的标准图片打破,和一个定性不同的挫折原子状态出现。这是赝能隙闭合以及杂质内和杂质间散射通道之间的相关精细Fano相互作用的结果。

英文摘要:

We theoretically analyze the effect of the inversion symmetry breaking on the structure of the impurity molecular states in Weyl metals. We show that for the case of a highly noncentrosymmetric Weyl metallic host, the standard picture of the alternating bonding and antibonding orbitals breaks down, and a qualitatively different frustrated atomic state emerges. This is a consequence of the pseudogap closing and related delicate Fano interplay between intra- and inter-impurity scattering channels.
