Fig. 5: More realistic band structure around Γ point.
From: The discovery of three-dimensional Van Hove singularity
The left and right panels are schematic plots of band structure along the in-plane \({k}_{\parallel }\) and out-of-plane \({k}_{z}\) directions, respectively. Orange (azure) curves denote the conduction (valence) bands. The proposed model might resolve controversies regarding the metallicity/insulativity of the EuCd2As2 system and explain the discrepancy in previous ARPES, transport, and optical results. The Weyl bands within the black dashed box are associated with the features in magneto-infrared spectroscopy. Red and blue dashed curves denote the band with opposite spin textures.
