hiPhive is a tool for efficiently extracting interatomic force constants (FCs) from atomistic simulations, most commonly density functional theory calculations, including higher-order FCs in large and/or low-symmetry systems. It is written in Python, which allows easy integration with countless first-principles codes and analysis tools accessible in Python including, e.g., phonopy, phono3py, and shengBTE, and allows for a simple and intuitive user interface. The FCs enable one to compute a variety of thermodynamic properties, including, e.g., phonon dispersions, effective harmonic models, self-consistent phonons, free energies, thermal conductivities or defect lineshapes.

icet is a tool for the construction and sampling of alloy cluster expansions. It is written in Python, which enables easy integration with many first-principles codes and analysis tools accessible from Python, and allows for a simple and intuitive user interface. It also includes functionality for, e.g., enumerating structures, mapping relaxed structures, special-quasi-random (SQS) and special-quasi-ordered structures (SQOS), handling constituent strain, ground state finding, as wells customizing cluster spaces, which is powerful for low-symmetry systems. The Monte Carlo (MC) module supports a variety of ensembles, including, e.g,. canonical, semi-grand canonical, variance constrained semi-grand canonical, and combinations thereof. It is moreover possible to compute various properties via the observer functionality.
