The odd-parity altermagnetism induced reconstruction of the Chern-insulating phase in Haldane-Hubbard model
This study investigated how odd-parity altermagnetism (ALM) reconstructs local topology within conventional Chern-insulating phases of the Haldane-Hubbard model. The key finding is that while local features like Berry curvature and edge states are significantly reshaped, the total Chern number remains unchanged. This establishes the Haldane-Hubbard model as a platform for odd-parity altermagnetic topology.
