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…
Dirac charge in antiferromagnetic topological semimetals
Kohei Hattori, Hikaru Watanabe, Ryotaro Arita
Topological node of electronic bands can carry emergent charge degree of freedom such as the Berry curvature monopole of the Weyl semimetals, which results in intriguing transport…
Nonlinear Hall effect driven by spin-charge-coupled motive force
Kohei Hattori, Hikaru Watanabe, Ryotaro Arita
Parity-time-reversal symmetric (-symmetric) magnets have garnered much attention due to their spin-charge coupled dynamics enriched by the parity-symmetry breaking. B…
Effect of collective spin excitation on electronic transport in topological spin texture
Kohei Hattori, Hikaru Watanabe, Junta Iguchi +2
We develop an efficient real-time simulation method for the spin-charge coupled system in the velocity gauge. This method enables us to compute the real-time simulation for the two…
