A Julian abstract interface for atomic structures.
AtomsBase is an abstract interface for representation of atomic geometries in Julia. It aims to be a lightweight means of facilitating interoperability between various tools including, e.g.,
- Simulation engines, e.g. molecular dynamics, geometry optimization, etc
- Computing chemical or mechanical properties, e.g., via DFT, or interatomic potentials,
- Integration with third party-libraries
- I/O with standard file formats (.cif, .xyz, ...)
- automatic differentiation and machine learning systems
- numerical tools: sampling, integration schemes, etc.
- visualization (e.g. plot recipes)
While AtomsBase focusses on representation of atomic systems, the sister package AtomsCalculators provides a general interface to compute properties of such systems.
Currently, the design philosophy is to be as lightweight as possible with a small set of required function dispatches to make adopting the interface easy. We also provide prototype implementations that we envision to be broadly applicable. If features beyond these are required we encourage developers to open PRs or provide their own implementations. For more on how to use the package, see the documentation.
