PLATO (computational chemistry)

PLATO (Package for Linear-combination of ATomic Orbitals) is a suite of programs for electronic structure calculations. It receives its name from the choice of basis set (numeric atomic orbitals) used to expand the electronic wavefunctions.

PLATO is a code, written in C, for the efficient modelling of materials. It is a tight binding code (both orthogonal and non-orthogonal), allowing for multipole charges and electron spin. It also contains Density Functional Theory programs: these were restored to enable clear benchmarking to tight binding simulations, but can be used in their own right. The Density Functional Tight Binding program can be applied to systems with periodic boundary conditions in three dimension (crystals), as well as clusters and molecules. [1] [2] [3] [4]

How PLATO works

edit

How PLATO performs Density Functional Theory is summarized in several papers: [5] [6] .[7] The way it performs tight binding is summarized in the following papers [8] [9]

Applications of PLATO

edit

Some examples of its use are listed below.

Metals

edit
  • Point defects in transition metals: Density functional theory calculations have been performed to study the systematic trends of point defect behaviours in bee transition metals.[10]

Surfaces

edit
  • Interaction of C60 molecules on Si(100):The interactions between pairs of C60 molecules adsorbed upon the Si(100) surface have been studied via a series of DFT calculations.[11]

Molecules

edit
  • Efficient local-orbitals based method for ultrafast dynamics: The evolution of electrons in molecules under the influence of time-dependent electric fields is simulated.[12]
