An application for first-principles calculation based on density functional theory (DFT) optimized for X-ray spectroscopy analysis. Theoretical prediction and data fitting for X-ray spectroscopy such as XANES(X-ray absorption fine structure), XMCD(X-ray magnetic circular dichroism), RXD(resonant X-ray diffraction) can be preformes. This application employs a fully relativistic LSDA calculation based on the finite element method, and also supports the LDA+U method and the TD-DFT calculation.
Open-source software for analyzing scientific data. DAWN can visualize data in various dimensions, from 1D to 3D, and it is also possible to create maps that plot different types of data. It can not only visualize data, but also process data, such as fitting for peak detection. It supports general data formats such as text files and HDF5, as well as data formats such as NeXus, which is used in X-ray experiments.
Open source Python package for data mining of materials. It can extract data from more than dozens of databases, perform preprocessing and visualization of extracted data. By combining machine-learning tools such as scikit-learn, users can build machine-learning models with descriptors created from the extracted data.
Analytical tool to calculate the Z2 topological number or Chern number from given band structures, which are derived from first-principles calculations or tight-binding Hamiltonians. The topological numbers are calculated from the evolution of Wannier charge center and this method is applicable to the systems without inversion symmetries.
A program for generating maximally-localized Wannier functions from results of first-principles calculation. This program supports Quantum Espresso, abinit, SIESTA, FLEUR, Wien2k, and VASP. It can also calculate electrical conductivity and material properties related to the berry phase from the obtained MLWFs.
A python library for materials analysis. Flexible classes for representation of materials are prepared, and data for crystal structures and various material properties can be handled efficiently. This application can performs analysis of phase diagrams, Pourbaix diagrams, diffusion analyses etc. as well as electronic structure analyses such as density of states and band structures. This software is being actively developed keeping close relation with Materials Project.
An application for prediction of stable and metastable structures from a chemical composition. For prediction of structures, this application combines the first-principles calculation by external packages (VASP, GULP, siesta, Quantum Espresso, STM4, CP2k, etc.) with various efficient algorithms such as the evolutionary algorithm.
It can be applied to prediction of, e.g., structure of crystals under extreme pressure, nanoparticles, and surface reconstruction.
An application for analysis of extended X-ray absorption fine structure (EXAFS) based on the multiple scattering theory. This application implements relativistic self-consistent calculation using the muffin-tin approximation to evaluate atomic phase shift including effect of neighboring atoms. Spectra with any number of edges can be treated simultaneously. Complex background multi-electron excitation can also be evaluated.
Software to calculate physical quantities related to phonon in solids from result calculated using first principles calculation software. Results calculated from first principles calculation software such as VASP and Wien2k are used as an input.
An open-source application for translating chemical structure format files. More than 110 formats are supported. This application is actively being developed taking into account use and construction of database and application to infomational technology in chemistry (chemoinformatics). A graphical user interface is alsp provided for Windows.
