PLATO (computational chemistry)

PLATO is a suite of programs for electronic structure calculations. It receives its name from the choice of basis set 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, allowing for multipole charges and electron spin. It also contains Density Functional Theory programs for building tight binding models. The Density Functional Tight Binding program can be applied to systems with periodic boundary conditions in three dimension, as well as clusters and molecules.

How PLATO works

How PLATO used to perform Density Functional Theory calculations is summarized in several papers:
. A new set of Density Functional Theory programs is being built making use of Gaussian orbital expansions for the basis set. The way PLATO performs tight binding simulations is summarized in the following papers:

Applications of PLATO

Some examples of the way it has been used are listed below.

Metals

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.

Surfaces

Interaction of C₆₀ molecules on Si:The interactions between pairs of C₆₀ molecules adsorbed upon the Si surface have been studied via a series of DFT calculations.

Molecules

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