ASE - Atomic Simulation Environment ASE is built around the Atoms object, which represents a collection of atoms with positions, atomic numbers, and a unit cell. It provides a common interface for interacting with various "Calculators" (external codes that compute energies and forces). When to Use - Building complex atomic structures: molecules, crystals, surfaces, and nanoparticles. - Running geometry optimizations (finding the minimum energy structure). - Performing Molecular Dynamics (MD) simulations in various ensembles. - Calculating Potential Energy Surfaces (PES) and transition states…
