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…
