Researchers have shown that nonlinear circular dichroism in second-harmonic generation is directly proportional to the local Berry curvature, enabling an ...

Physicists discovered that the antiferromagnet UOTe spontaneously forms a chiral superlattice of frozen phonons that generates giant Berry curvature, a ...

Physicists report a record anomalous Hall conductivity in the kagome antiferromagnet YMn6Sn6, driven by field-induced spin canting that reshapes momentum-space ...
