Exact diagonalization provides evidence that the antiferromagnetic Chern insulator phase with quantized Chern number C=1 exists in the Kane-Mele-Hubbard model, shown by gap closing, anisotropic spin correlations, fidelity susceptibility, and a modified Chern number calculation that accounts for TRS-
