A results database of first-principle calculation for material science. This database provides numerical data of crystal structures, band structures, thermodynamic quantities, phase diagrams, magnetic moments, and so on. This site is maintained by a research group of Duke University, and in particular, has extensive data of Heusler alloys. In addition to a user interface based on web browsers, an http-based API is also provided to enable user-defined material screening. This database can be used without charge after registration.
An open-source application for molecular dynamics. This application can perform molecular dynamics simulation of biopolymers and solvents consisting of a number of molecules/atoms. It implements a number of force field sets and algorithms, and supports parallel computing based on OpenMP. Java graphical user interface (GUI) is also included.
An application program for lattice dynamics calculation of molecules, surfaces, and solids in various boundary conditions. It lays emphasis on analytic calculation of lattice dynamics while it can perform molecular dynamics simulation as well. It supports various force fields to treat ionic materials, organic materials, and metals. It also implements analytic derivatives of the second and third order for many force fields.
An application for modeling and visualization of molecules for quantum chemical calculation. This application implements a construction of
molecular structures with classical molecular dynamics simulation and structure optimization by simple generic force fields, and a preparation of input files for applications of quantum chemical calculation such as Gaussian. A binary package for Windows XP is available, and informal packages for Windows 7, iPad, and Linux exist.
Payware for ab initio quantum chemical calculation. This application performs high-speed quantum chemical calculation based on the density functional, Hartree-Fock theory, and MP2 theories. It can perform structure optimization, spectrum analysis, evaluation of acid dissociation constants, and so on. It can treat excited states by using TDDFT and CIS. Maestro, an application for visualization produced by the same developer, provides a useful interface for Jaguar.
An open-access database of crystal structures. This database includes structural data of organic, inorganic, metal-organic compounds and minerals. At the end of 2017, this database contains about 400,000 entries. Three-dimensional structures of crystals can be viewed by GUI on the web.
A first-principles simulation program based on the pseudopotential method utilizing Gaussian basis sets. It can perform simulations based on Hartree-Fock and density functional theories. It can be run under Unix/Linux, and also provides a simple GUI for Windows. Binaries are distributed for a fee, but users can first try the evaluation copy.
Program package for first-principles calculation based on all-electron calculation method and augmented plane-wave basis. This package performs electronic-state calculation such as band calculation of solids, structure optimization, first-principles molecular dynamics, and so on. All-electron method, which treats core electrons, improves accuracy in calculation compared with pseudo-potential method, and enables us to obtain chemical shifts related to core electrons. This payware can be used by making a contract with the developer.
