Chern-Insulator Phase in Antiferromagnets
The long-sought Chern insulators
that manifest a quantum
anomalous
Hall effect are typically considered to occur in ferromagnets. Here,
we theoretically predict the realizabilities of Chern insulators in
antiferromagnets, in which the magnetic sublattices are connected
by symmetry operators enforcing zero net magnetic moment. Our symmetry
analysis provides comprehensive magnetic layer point groups that allow
antiferromagnetic (AFM) Chern insulators, revealing that an in-plane
magnetic configuration is required. Followed by first-principles calculations,
such design principles naturally lead to two categories of material
candidates, exemplified by monolayer RbCr4S8 and bilayer Mn3Sn with collinear and noncollinear AFM
orders, respectively. We further show that the Chern number could
be tuned by slight ferromagnetic canting as an effective pivot. Our
work elucidates the nature of the Chern-insulator phase in AFM systems,
paving a new avenue for designing quantum anomalous Hall insulators
with the integration of nondissipative transport and the promising
advantages of the AFM order

Singularity Types for Long-Time Chern-Ricci Flow
We extend some results known for the Kähler-Ricci flow to the Chern-Ricci flow regarding the independence of singularity types for long-time solutions. Specifically, we show that if a solution to the Chern-Ricci flow exists with uniformly bounded torsion and curvature, then any other solution starting from an initial metric of the same class will also exhibit uniform bounds on torsion and curvature.13 pages, any comments welcome
