An open-source application for the first-principles calculation by the all-electron calculation method based on plane wave bases. In addition to standard methods (LDA, GGA, etc.), the LDA+U method, treatment of spin-orbit interaction (noncolinear magnetism), and calculation of phonons are supported. Hybrid parallel computing by OpenMP and MPI is also supported.
An application for electronic structure calculations and molecular dynamics simulations based on tight-binding approximation. By the Krylov subspace method, this application performs order-N electronic state calculation for large physical systems including a large number of atoms. It also supports massively-parallel computation using MPI/openMP hybrid parallelism, and has demonstrated calculation of 10^7-atom simulation on the K Computer.
Payware for general-purpose visualization of outputs produced by various scientific computing solvers. This application visualizes simulation results of various applications, including ANSYS, for fluid dynamics, structure analysis, granular material analysis, solidification analysis and so on. It can treat large-scale data, and can make animation with various options such as flipbook animation, surface/contour moving, elastic load display, and modification display of mode shapes.
ERmod is software for calculating the free energy in soft, molecular aggregate. This program rapidly and accurately calculates the free energy of binding of a molecule in the aggregate through combination of the molecular dynamics simulation and the energy-representation theory of solvation. The solubility of a molecule can be determined with ERmod in arbitrary solvent including supercritical fluid and ionic liquid. Assessment is also possible for the binding strength and site of a molecule in micelle, lipid membrane or protein.
An application for structure prediction based on the evolutionary algorithm. From an input of the atomic position in a unit cell and possible elements at each atomic position, this application predicts the stable structure and composition from the first-principles calculation and molecular dynamics in combination with the evolutionary algorithm. This application is written in Python, and uses Quantum ESPRESSO and GULP as an external program.
Exabyte.io is a cloud-based nano-scale material modeling platform that accelerates research and development of new materials. Material science softwares such as Quantum ESPRESSO have been implemented on this platform, which can be used through web-page or via secure shell terminal.
An open-source application for first-principles calculation based on all-electron calculations. In addition to ground-state energy and forces on atoms obtained by density functional theory, it focuses on investigation of excited state properties using time-dependent density functional theory as well as many-body perturbation theory. It is parallelized using MPI and is also optimized for multithreaded math libraries such as BLAS and LAPACK.
An application for molecular modeling and visualization. This application can be used in cooperation with other applications such as TINKER, MSMS, Firefly, GAMESS, MOPAC, and Gaussian. In particular, this application is essential to visualization of the FMO calculation in GAMESS. It also supports graphical user interface for input-file preparation, dynamic image presentation of normal-mode vibration, and visualization of energies and structures near transition states.
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.
