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…
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…
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…
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…
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…
