Physics of domains and domain walls in topological magnets

 · Invited

Abstract

We will discuss the energetics and dynamics of domains and the boundaries between them in two examples of topological magnets: antiferromagnetic Weyl metals, as exemplified by Mn3Sn, and quantum anomalous Hall states as is observed in twisted bilayer graphene. The two cases will be distinctly contrasted and compared, and implications for experiments outlined.

*The work on Mn3Sn was supported by the NSF CMMT program under Grants No. DMR1818533, and that on QAHE by the DOE, Office of Science, Basic Energy Sciences under Award No. DE-FG02-08ER46524.
