octopus is a program aimed at the ab initio virtual experimentation on a hopefully ever increasing range of systems types. Its main characteristics are:
- Electrons are describe quantum-mechanically within the Density-Functional Theory (DFT), in its time-dependent form (TDDFT) when doing simulations in time. Nuclei are described classically as point particles.
- Electron-nucleus interaction is described within the Pseudopotential approximation.
