Advance / NanoLabo is an integrated GUI which can graphically operate various calculation solvers such as Quantum ESPRESSO, LAMMPS, Advance / PHASE. It is easy to set modeling and calculation conditions by automatically searching information in typical materials databases such as Materials Project. Results calculated by solvers are graphically displayed instantaneously.
A program package for constructing interatomic force fields which explicitly consider lattice anharmonicity. In combination with an external first-principles package such as VASP or xTAPP, ALAMODE extracts harmonic/anharmonic force constants of solids and calculate phonon dispersion, phonon DOS, Gruneisen parameter, phonon-phonon scattering probability, lattice thermal-conductivity, and so on.
An application for calculating thermal transport properties based on the phonon Boltzman equation. This application has its own database for phonon properties of materials, and can utilize it for evaluating heat conductivity and specific heat of crystals, alloys, and heterostructures combining them. Phonon-energy resolved contribution to heat conductivity and specific heat can also be calculated. This application also supports calculation of time-dependent response and steady state analysis.
A set of tools for alloy theory analysis in combination with first-principles calculation packages. Free energy and thermodynamic phase diagrams of alloy systems are calculated by combining the cluster expansion method with Monte Carlo simulations. Interfaces with major first-principles code including Quantum Espresso, VASP, and ABINIT are provided.
A set of python modules for modeling atomic structures, running simulations, and visualizing results. These modules provide interfaces for various application of first-principles calculation, classical molecular dynamics, and quantum chemical calculation through GUI, command line, or python scripts. The source code is available under the LGPL.
A tool for performing Bader analysis of assigning electron density of molecules and solids to individual atoms. Binaries for Linux and Mac OS X, as well as source code is provided under the GPL. The code is written in fortran90, and can handle charge density data in VASP CHGCAR and Gaussian Cube formats.
BerkeleyGW is an open-source program package to calculate quasi-particle spectrum and optical responses from mean-field result by using GW approximation and Bethe-Salpeter equation. This is compatible with output files of many commonly used DFT codes such as Quantum ESPRESSO.
Web server that offers various crystallographic tools free of charge. The server offers over 70 tools/utilities related to space group, magnetic space group, representation theory, scattering theory, etc. The tools are accessed through a web interface.
An application for calculating transport coefficients based on the Boltzman equation. Within the relaxation time approximation, transport coefficients such as the Hall coefficient and the Seebeck coefficient can be evaluated from the output of the first principles calculation applications (Wien2k, ABINIT, SIESTA, quantum ESPRESSO, VASP). If users can measure relaxation time experimentally, electric conductivity can also be evaluated.
Fitting data to a scaling law of critical phenomena, we automatically estimate critical point and indices. Since Bayesian method is flexible, we can use all data in a critical region.
