Chiral Phonons in a Cubic Lattice
Hirokazu Tsunetsugu, Hiroaki Kusunose
We have developed a theory for the energy dispersion of chiral phonons in a simplest cubic lattice. Among all the phonon modes, only the optical triplet modes exhibit the intrinsic…

Orbital moiré and quadrupolar triple-q physics in a triangular lattice
K. Hattori, T. Ishitobi, H. Tsunetsugu
We numerically study orders of planer type quadrupoles on a triangular lattice with nearest-neighbor isotropic and anisotropic interactions. This type of qua…
