z-Pares is an app for obtaining the eigenvalues and eigenvectors for general sparse matrices using the contour integrals in the complex plane, i.e., Sakurai-Sugiura method. z-Parels is written in fortran 90/95 and supports the large scale parallelization via the two-level MPI distributed parallelism.
An application for micromagnetic simulation optimized for industrial use of magnetic device design. This application can simulate read-out/write-in by a disk head in a hard disk device, magnetic recording media, and spatial profiles of magnetization in MRAM devices. This application also implements long-time simulation by a Monte Carlo method, treatment of thermal noise, and modeling of granular structures.
A program package for physical properties related to magnetism. This application can evaluate various physical quantities of magnetics such as crystal fields, magnetic structures, thermodynamic quantities (magnetization, specific heat, etc.), and magnetic excitation. This package can also perform fitting analysis of neutron diffraction experiments and resonant X-ray diffraction experiments, and is helpful to experimentalists.
An application for first-principles calculation based on density functional theory. This application is included in Material Sudio, and can evaluate electronic states and properties of various physical systems such as molecules, atomic clusters, crystals, and solid surfaces based on the all-electron method and the pseudopotential method. It can also be applied to evaluation of the chemical reaction such as catalysis and combustion reaction, and is optimized for large-scale parallel computing.
WEST is a package for calculating excited spectrum by using the one-shot GW method. Before calculating the excited spectrum, it is necessary to obtain the ground states from the DFT calculations (LDA/GGA/hybrid functional) by Quantum ESPRESSO. To reduce the numerical cost, WEST uses the algorithm that does not require the unoccupied bands. It is also possible to include the spin-orbit couplings and to perform the large-scale calculations at supercomputers. Installation and formats of input files are basically the same as those of Quantum ESPRESSO.
An open source library to calculate free energy in molecular dynamics simulation. It supports several famous molecular dynamics software packages such as Amber and Lammps.
An interface package to use Torch (the open-source numerical library for machine learning) from Python. Users can easily implement deep learning based on neural networks, and can use various state-of-the-art methods. This package supports GPGPU parallel computation, and realises high-speed operation. A front-end interface for C++ is also prepared.
Open-source package for first-principles calculation based on pseudo-potential and plane-wave basis. This package performs various electronic-state calculation by density functional theory such as band calculation of solids, and structure optimization of surfaces/interfaces. Detailed tutorials and documents are well prepared in this package, and many physical quantities including chemical reaction and lattice vibration can be obtained easily.
An application for three-dimensional visualization with the ray tracing method. This application can visualize arbitrary positions and shapes of objects such as spheres and cubes. It can visualize three-dimensional data obtained from computational fluid dynamics etc. by volume rendering. It can also be used for simple three-dimensional graphical simulator with macro functions.
Elastic is a set of python routines for calculation of elastic properties of crystals (elastic constants, equation of state, sound velocities, etc.). It is implemented as a extension to the Atomic Simulation Environment (ASE) system. There is a script providing interface to the library not requiring knowledge of python or ASE system.
