Matrix Product Toolkit

  • Level of openness 3 ★★★
  • Document quality 3 ★★★

A program package for numerically solving effective lattice models using matrix product states (MPS). The ground state of a one-dimensional quantum system and its time evolution can be numerically evaluated by using an infinite system algorithm based on MPS. Useful tutorials and examples of calculations are also provided.

DCore

  • Level of openness 3 ★★★
  • Document quality 3 ★★★

A tool for performing quantum many-body simulations based on dynamical mean-field theory. In addition to predefined models, one can construct and solve an ab-initio tight-binding model by using wannier 90 or RESPACK. We provide a post-processing tool for computing physical quantities such as the density of state and the momentum resolved spectral function. DCore depends on external libraries such as TRIQS and ALPSCore.

Questaal

  • Level of openness 3 ★★★
  • Document quality 3 ★★★

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.

FDMNES

  • Level of openness 3 ★★★
  • Document quality 3 ★★★

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.
