Advance / PHASE is a software for first-principles calculation based on the density functional theory by using plane-wave basis and pseudopotentials. Since the electronic state is obtained based on quantum mechanics, highly accurate results can be obtained. It can be expected not only to analyze existing materials but also to design various metals, insulators, semiconductors, magnetic materials, dielectric materials, piezoelectric materials, and various other new materials.
AkaiKKR is a first-principles all-electron code package that calculates the electronic structure of condensed matters using the Green’s function method (KKR). It is based on the density functional theory and is applicable to a wide range of physical systems. It can be used to simulate not only periodic crystalline solids, but also used to calculate electronic structures of impurity systems and, by using the coherent potential approximation (CPA), random systems such as disordered alloys, mixed crystals, and spin-disordered systems.
Payware for evaluation of electron transport based on nonequilibrium Green’s function. This application is descended from the SIESTA application, and can calculate electronic transport properties of bulk materials and molecules inserted between leads by performing electronic state calculation under a finite bias. One can choose either density functional method or semiempirical method, and can control external factors such as gate voltages. It also implements structure optimization and analysis of chemical reaction paths.
