An interface tool for combining first-principles calculation based on density functional theory (DFT) and TRIQS, the application for dynamical mean-field theory (DMFT). By combining Wien2k and TRIQS, self-consistent DFT+DMFT calculation can be realized by this tool. One-shot DFT+DMFT calculation using band structures obtained by other first-principles applications is also possible.
Ab initio quantum Monte Carlo solver for both molecular and bulk electronic systems. By using the geminal/Pfaffian wavefunction with the Jastrow correlator as the trial wavefunction, users can perform highly accurate variational calculations, structural optimizations and ab initio molecular dynamics for both classical and quantum nuclei.
Application for performing first-principles simulations with an implicit solvent model. The code is released as a patch to VASP. The user can perform molecular dynamics as well as reaction analysis using e.g., nudged elastic band method.
WannierTools is an open-source software package for investigation of novel topological materials. This code works in the tight-binding framework, which can be generated by another software package Wannier90. Users can perform calculations of the Wilson loop, positions of Weyl/Dirac points, nodal line structures, andthe Berry phase around a closed momentum loop and Berry curvature in a part of the Brillouin zone.
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.
Program package for first-principles calculation based on all-electron calculation method and augmented plane-wave basis. This package performs electronic-state calculation such as band calculation of solids, structure optimization, first-principles molecular dynamics, and so on. All-electron method, which treats core electrons, improves accuracy in calculation compared with pseudo-potential method, and enables us to obtain chemical shifts related to core electrons. This payware can be used by making a contract with the developer.
xTAPP is a first-principles plane-wave pseudo-potential code. It computes band structure and electronic states with high precision for a wide range of materials including metals, oxide surfaces, solid interfaces, and so forth. It has support tools and visualization of output and input, is available as a massively parallel computer using OpenMP, MPI, and GPGPU.
Code for performing many-body calculations based on the GW method, BSE method, etc. starting from Kohn-Sham wave functions obtained using density functional theory. The code relies on wave function output from either abinit or Quantum Espresso. A python interface, Yambo-py, is also under development.
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.
