Chirality/Axiality-Induced Axiality/Chirality via Surface Polarization
Satoru Hayami, Rikuto Oiwa, Akane Inda
In condensed matter physics, a broad spectrum of physical characteristics, such as chirality, axiality, and polarity, arises as a direct consequence of the underlying symmetry of t…
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…
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…
Scalar spin chirality induced by a circularly polarized electric field in a classical kagome magnet
Ryota Yambe, Satoru Hayami
Noncoplanar magnetic states with a scalar spin chirality have been intensively studied in condensed matter physics, since they exhibit fascinating physical phenomena. We theoretica…
Analysis of photo-induced chirality and magnetic toroidal moment based on Floquet formalism
Satoru Hayami, Ryota Yambe, Hiroaki Kusunose
We analyze the condition of photo-induced atomic-scale chirality and magnetic toroidal moment. By performing a high-frequency expansion in the Floquet formalism, we derive an effec…
Magnetic instability under ferroaxial moment
Akane Inda, Satoru Hayami
Magnetic anisotropy is one of the important factors in determining magnetic structures. A type of magnetic anisotropy is closely related to the symmetry of crystals. We theoretical…
Classification of multipoles induced by external fields and currents under electronic nematic ordering with quadrupole moments
Satoru Hayami
We theoretically investigate the effect of external fields and currents on electronic nematic orderings based on the concept of augmented multipoles consisting of electric, magneti…
Pseudogap and Fermi arc induced by Fermi surface nesting in a centrosymmetric skyrmion magnet
Yuyang Dong, Yuto Kinoshita, Masayuki Ochi +12
Skyrmions in noncentrosymmetric materials are believed to occur due to the Dzyaloshinskii-Moriya interaction. By contrast, the skyrmion formation mechanism in centrosymmetric mater…
