Effective phonon models based on symmetry-adapted multipole basis -- Hidden chiral phonon angular momentum splitting in ferroaxial systems
Yu Xie, Rikuto Oiwa, Satoru Hayami
We propose a symmetry-based framework for constructing effective harmonic phonon models using a symmetry-adapted multipole basis. By decomposing the force-constant matrix into bond…
Antiparallel spin polarizations as quadratic response in chiral systems
Akane Inda, Kohei Hattori, Hiroaki Kusunose +1
Chirality-dependent spin generation has attracted considerable attention in condensed matter physics. In this paper, we theoretically investigate antiparallel spin polarization as…
Nonrelativistic Functional Properties in Collinear Antiferromagnets Based on Multipole Representation Theory
Yuuki Ogawa, Satoru Hayami
In recent years, the concept of multipoles has been widely used to describe and classify various magnetic and electric responses in solids, providing a systematic way to identify s…
Symmetry classification of magnetic octupole current based on multipole representation theory
Yuuga Takasu, Satoru Hayami
Magnetic octupole (MO) currents have recently attracted significant attention as a driving force for the Neel vector dynamics in d-wave altermagnets, a new class of antiferromagnet…
Analysis of Spin Current Generation by Elastic Waves in -wave Altermagnets
Ken Uchino, Yuuki Ogawa, Satoru Hayami
We theoretically investigate the mechanism of spin current generation induced by elastic waves in nonrelativistic magnets referred to as altermagnets. By analyzing an -wave alte…
