Orbital paramagnetism without density of states enhancement in nodal-line semimetal ZrSiS
Soshun Ozaki, Hiroyasu Matsuura, Ikuma Tateishi +2
Unconventional orbital paramagnetism without enhanced density of states was recently discovered in the nodal-line semimetal ZrSiS. We propose a novel interband mechanism, linked to…
Ideal Spin-Orbit-Free Dirac Semimetal and Diverse Topological Transitions in PrCoGa Family
Manabu Sato, Juba Bouaziz, Shuntaro Sumita +5
Topological semimetals, known for their intriguing properties arising from band degeneracies, have garnered significant attention. However, the discovery of a material realization…
Topological invariant and domain connectivity in moiré materials
Ikuma Tateishi, Motoaki Hirayama
Recently, a moiré material has been proposed in which multiple domains of different topological phases appear in the moiré unit cell due to a large moiré modulation. Topological pr…
Electronic topological transition of 2D boron by the ion exchange reaction
Xiaoni Zhang, Yuki Tsujikawa, Ikuma Tateishi +8
We systematically investigated electronic evolutions of non-symmorphic borophene with chemical environments that were realized by the ion exchange method. Electronic structures can…
Quantum spin Hall effect from multi-scale band inversion in twisted bilayer Bi(TeSe)
Ikuma Tateishi, Motoaki Hirayama
Moiré materials have become one of the most active fields in material science in recent years due to their high tunability, and their unique properties emerge from the Moiré-scale…

The bulk properties of nodal line materials have been an important research topic in recent years. In this paper, we study the orbital magnetic susceptibility and the Hall conducti…
Nodal lines and mapping to mirror Chern numbers in CaAs family
Ikuma Tateishi
We study topological properties of materials in the CaAs family without spin-orbit coupling (SOC) by combining the first-principles calculation and a tight-binding model calcul…
Mapping rules from nodal line semimetal to topological crystalline insulator in face centered cubic lattice
Ikuma Tateishi
We study what kind of topological crystalline insulator phase emerges from nodal line semimetal phases in the face-centered cubic system which is not indicated by topological indic…
Face centered cubic SnSe as a trivial Dirac nodal line material
Ikuma Tateishi, Hiroyasu Matsuura
The presence of a Dirac nodal line in a time-reversal and inversion symmetric system is dictated by the index when spin-orbit interaction is absent. In a first princ…
