  "abstract": "The anomalous Hall effect (AHE) in non-magnetic materials is a powerful transport probe of the Berry curvature (BC) of Bloch electrons and a key component of next-generation spintronic devices. In this work, I present a first-principles study of the anomalous Hall conductivity (AHC) in monolayer AlPd5I2, a two-dimensional material hosting a Dirac-type crossing located close to the Fermi energy. Density functional theory (DFT) with spin-orbit coupling (SOC) is performed using Quantum ESPRESSO and maximally localized Wannier functions (Wannier90). The electronic structure reveals a Dirac point at the S point, split by SOC into a gapped state with a large BC. The Fermi level is located slightly above the gap, yielding a metallic state with a very high AHC. The AHE is traced directly to the intense BC hotspots at the SOC-induced gap at the Dirac point. My findings establish the AlPd5I2 monolayer as a promising system for investigating BC dominated transport and large Hall responses.",
