ABIDEV 2024

Established in 2002, the ABINIT Developer Workshops convene individuals actively engaged in the advancement of the ABINIT application and associated software. The primary objectives include discussing the overarching framework of the package and its potential evolution, presenting recent implementations' formalism and technical intricacies, coordinating short-term development plans, and strategizing long-term goals.

ABINIT, an open-source software, specializes in atomistic modeling of periodic solids and nanostructures. This international initiative engages contributors worldwide, boasting over 1300 registered users and approximately 40 yearly contributors. With over 700,000 lines of source code, ABINIT's main program facilitates first-principles determination of total energy, charge density, electronic structure, and other properties using pseudo-potentials or the Projector Augmented-Wave (PAW) method alongside plane-wave or wavelet bases. Its core theories encompass Density-Functional Theory (DFT) for ground-state calculations, Density-Functional Perturbation Theory (DFPT) for response function calculations, and Many-Body Perturbation Theory (MBPT) for excited-state computations.

Thanks to its open-source nature, ABINIT integrates seamlessly with various atomistic modeling software projects through shared libraries or common file formats. The software capitalizes on efficient parallelism, supporting key functionalities like ground state DFT, phonon band structure calculations, and GW calculations. Additionally, a GPU-accelerated version of ABINIT is available for enhanced performance.
