Chiral Photocurrent in Parity-Violating Magnet and Enhanced Response in Topological Antiferromagnet
Hikaru Watanabe, Youichi Yanase
Abstract
A new classification of photocurrent responses in light of symmetry violations in the presence of magnetic order unveils two new types of photocurrent that can be readily tuned and enhanced by topological electronic structure in solids.
