Nonlinear Piezomagnetic Effects in -wave Altermagnets
Yuuki Ogawa, Satoru Hayami
We theoretically study the generation of net magnetization induced by static strain in -wave altermagnets, which exhibit the symmetric spin-split band structure under collinear…
Emergent cross-product-type spin-orbit coupling under ferroaxial ordering
Akane Inda, Satoru Hayami
A ferroic alignment of a time-reversal-even axial vector, which is called the ferroaxial ordered state, is identified by the spontaneous rotational distortion of the lattice struct…
Unified description of electronic orderings and cross correlations by complete multipole representation
Satoru Hayami, Hiroaki Kusunose
We overview recent developments of electronic orderings and associated cross correlations in condensed matter physics based on a complete set of multipole representations (electric…
Dynamical generation of skyrmion and bimeron crystals by a circularly polarized electric field in frustrated magnets
Ryota Yambe, Satoru Hayami
A skyrmion crystal (SkX) has attracted much attention in condensed matter physics, since topologically nontrivial structures induce fascinating physical phenomena. The SkXs have be…
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…
Quantification of chirality based on electric toroidal monopole
Akane Inda, Rikuto Oiwa, Satoru Hayami +2
Chirality ubiquitously appears in nature, however, its quantification remains obscure owing to the lack of microscopic description at the quantum-mechanical level. We propose a way…
