Dirac Charge in Antiferromagnetic Topological Semimetals

Author(s): Kohei Hattori, Hikaru Watanabe, and 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 and optical phenomena. In this Letter, we discuss the existence of the hidden “Dirac charge” and its detection via the p… [Phys. Rev. Lett. 136, 046603] Published Fri Jan 30, 2026
