This package can perform molecular dynamics calculation of various systems such as soft matters, solids, and mesoscopic systems. It can be used as a simulator of classical dynamics of realistic atoms as well as general model particles. It supports parallel computing through spatial divisions. Its codes are designed so that their modification and extension are easy.
GPU library for pdgemm and pzgemm, which are functions of matrix-matrix operations in ScaLAPACK.
An application for first-principles calculation based on the all-electron method. This application implements not only normal electronic state calculation (band calculation) but also a quasi-particle GW method for self-consistent (or one-shot) calculation of excitation spectrum and quasi-particle band. Combining with dynamical mean-field theory, self-consistent calculation including many-body effect can also be performed.
An open source library for implementing tensor networks. It is developed based on TensorFlow and is designed to be easily used by experts in the field of machine learning as well as in the field of physics. In addition to TensorFlow, it includes wrappers for JAX, PyTorch, and Numpy.
An open-source application for first-principles calculation based on pseudopotential and wavelet basis. Electronic state calculation of massive systems is performed with high accuracy and high efficiency by using adaptive mesh. Parallel computing by MPI, OpenMP, and GPU is also supported.
This application can produce input files of various applications for density functional theory (DFT) calculations via user-friendly parameter adjustment using three-dimensional computer graphics (3DCG) and graphical user interfaces (GUI). Input-file conversion between different applications is also possible.
An open-source application for quantum chemical calculation. This application can perform quantum chemical calculation based on the Hartree-Fock method and the density functional method. The code is developed on the emphasis of readability and flexibility, and can be called from Python scripts. Quantum chemical calculation based on two-electron wave functions (geminals) is also possible.
A tool of input-file preparation and visualization for xTAPP, an application of the first-principle calculation. By graphical user interface (GUI), this application helps xTAPP users for making input files, and visualizes results of wavefunctions, electron densities, and potential profiles into three-dimensional graphics from output files.
An open-source application for micromagnetic simulation optimized for general-purpose computing on GPU. This application can calculate spatial distribution of magnetization with speed of more than 100 times compared with CPU calculation. This application can also treat the RKKY interaction, effect of spin injection, and Voronoi diagrams. It supports remote computing using its web-GUI system.
An open-source application for first-principles molecular dynamics based on a pseudopotential method using plane bases. This application can perform electronic-state calculation and molecular dynamics employing the Car-Parrinello method. It implements MPI parallelization, which enables us to perform efficient parallel computing in various environments including large-scale parallel computers. The program is written in C++, and is distributed in source form under the GPL license.
