| Full description | 'octopus' is a computer package for the si … 'octopus' is a computer package for the simulation of the electron-ion dynamics of finite systems in one and three dimensions under the influence of time-dependent electromagnetic fields. The electronic degrees of freedom are treated quantum mechanically within the time-dependent Kohn-Sham formalism, while the ions are handled classically. All quantities are expanded in a regular mesh in real-space; the simulations are performed in real-time. 'octopus' can also obtain static properties like ground-state geometries or static polarizabilities although it is not optimzed for this). The method employed proved quite reliable and general, and has been successfully used to calculate linear and non-linear absorption spectra, harmonic spectra, laser induced fragmentation, etc. of a variety of systems, from small clusters to medium sized quantum dots. all clusters to medium sized quantum dots. |
