An application for first-principles calculation based on the all-electron method with localized bases. Compared with the standard all-electron method (the full-potential LAPW method), this application uses a less number of bases keeping accuracy of calculation, and realize high-speed electronic state calculation by the density functional method. This application also supports calculation for disordered structures by coherent potential approximation (CPA), relativistic effect, and the LSDA+U method.
First-principles software based on plane-wave basis and norm-conserving pseudopotential methods. Time-dependent DFT has been implemented. Users can perform real-time simulations for electron-ion dynamics under a time-dependent external field. Pseudopotentials with FPSEID21 format should be used, and those are downloadable from the website.
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.
An open-source application for first-principles calculation based on the PAW method. By utilizing real-space or atom-localized basis sets, this application performs electronic structure calculation based on the density functional theory as well as the GW approximation. Simulations are set up using the interface provided by Atomic Simulation Environment (ASE). The code is written in C and python, and is available under GPL.
A graphical user interface (GUI) program for pre- and post-processing for the DFT package SIESTA. It allows visualizing band structures and density of states obtained by SIESTA and editing atom configurations. Structure data can also be output in input file formats compatible with other DFT packages such as VASP, CRYSTAL, and Quantum ESPRESSO.
H-wave is a Python package for performing unrestricted Hartree-Fock (UHF) calculations and random phase approximation (RPA) calculations for itinerant electron systems. H-wave supports UHF calculations both in real- and wavenumber-spaces. H-wave supports one-body and two-body interactions in the Wannier90 format as inputs for H-wave, and thus users can solve ab initio effective Hamiltonians derived from Wannier90/RESPACK calculations based on UHF and RPA methods.
