Correlated topological-polarization surface states in the narrow-gap insulator FeSb2
Takahiro Iwagaki, Hideki Matsuoka, Ginta Hoshino +7
Strong electron correlations and band topology each generate rich quantum phases, but conflicting elemental requirements have largely kept them apart. Topological polarization offe…
Carrier-density dependence of magnetotransport in correlated Dirac semimetal CaIrO
Rinsuke Yamada, Jun Fujioka, Minoru Kawamura +8
We report the carrier density dependence of the magnetotransport property in the correlated Dirac semimetal CaIrO. In the dilute carrier density region ( $\sim 2.2 \…
Unraveling a chemical-bond-driven root of topology in three-dimensional chiral crystals
Shungo Aoyagi, Shunsuke Kitou, Yuiga Nakamura +6
Chirality manifests across multiple scales, yielding unique phenomena that break mirror symmetry. In chiral materials, unexpectedly large spin-filtering or photogalvanic effects ha…
Designing single and degenerate flat bands in the kagome lattice with long-range hopping
Yuta Taguchi, Motoaki Hirayama, Takashi Miyake
We investigate the electronic structure of the kagome lattice model with first, second, and two kinds of third nearest-neighbor hoppings. We reveal that by tuning the third nearest…
