Predominant Electronic Order Parameter for Structural Chirality -- Role of Spinless Electronic Toroidal Multipoles
Rikuto Oiwa, Hiroaki Kusunose
We discuss predominant order parameters for structural chirality, and demonstrate that time-reversal-even axial-quadrupole plays a key role in stabilizing a chiral structure. Using…

Symmetry-adapted closest Wannier modeling based on complete multipole basis set
Rikuto Oiwa, Akane Inda, Satoru Hayami +3
We have developed a method to construct a symmetry-adapted Wannier tight-binding model based on the closest Wannier formalism and the symmetry-adapted multipole theory. Since the s…

Toroidal orders and related phenomena in nonmagnetic and magnetic materials
Hiroaki Kusunose, Satoru Hayami
In this short article, we overview a concept of electronic toroidal multipoles, and their ordering with associated physical properties in non-magnetic and magnetic materials. The t…
