DESCRIPTION
C-BerryTrans is a C++ based code designed for first-principles calculation of Berry-curvature-driven anomalous transverse transport properties, namely the anomalous Hall conductivity (AHC) and anomalous Nernst conductivity (ANC). The code directly extracts eigenvalues and momentum matrix elements from the WIEN2k package and evaluates the Berry curvature using a Kubo-like formalism, thereby avoiding interpolation errors associated with Wannier-based methods. To ensure efficiency, the code parallelizes Berry curvature evaluation over k-points using OpenMP and stores band-resolved data in binary format, enabling rapid post-processing of AHC and ANC across a wide range of chemical potentials and temperatures in a single run.
