Universal Role of Combined Symmetry for the Protection of the Dirac Cone in Antiferromagnetic Topological Insulators
Asuka Honma, Noriyuki Kabeya, Seigo Souma +13
Antiferromagnetic topological insulators (AF TIs) are predicted to exhibit exotic physical properties such as gigantic optical and topological magnetoelectric responses. While a ke…
Antiferromagnetic topological insulator with selectively gapped Dirac cones
A. Honma, D. Takane, S. Souma +14
Antiferromagnetic (AF) topological materials offer a fertile ground to explore a variety of quantum phenomena such as axion magnetoelectric dynamics and chiral Majorana fermions. T…
Unusual surface states associated with the PT-symmetry breaking and antiferromagnetic band folding in NdSb
Asuka Honma, Daichi Takane, Seigo Souma +8
We have performed micro-focused angle-resolved photoemission spectroscopy on NdSb which exhibits the type-I antiferromagnetism below TN = 16 K. We succeeded in selectively observin…
Signature of band inversion in the antiferromagnetic phase of axion insulator candidate EuIn2As2
Takafumi Sato, Zhiwei Wang, Daichi Takane +12
We have performed angle-resolved photoemission spectroscopy on EuIn2As2 which is predicted to be an axion insulator in the antiferromagnetic state. By utilizing soft-x-ray and vacu…
Observation of inverted band structure in topological Dirac-semimetal candidate CaAuAs
Kosuke Nakayama, Zhiwei Wang, Daichi Takane +13
