  • Level of openness 3 ★★★
  • Document quality 1 ★☆☆

An open-source application for simulation of low-dimensional interacting electron models based on density-matrix renormalization group (DMRG). For effective models of one-dimensional quantum systems and impurity systems, this application can treat not only physical quantities of ground states but also time evolution and finite-temperature physical quantities. The program is coded in C++, and can be called from MATLAB scripts.

Molden

  • Level of openness 3 ★★★
  • Document quality 2 ★★☆

An open-source application for pre- and post-processing for quantum chemistry calculation. This application can handle outputs from Gaussian, GAMESS, and MOPAC as well as the result of other applications via the Molden format. It supports many graphical interfaces such as Postscript, XWindows, VRML, and OpenGL, and performs visualization of molecular orbitals and electron density. It also produces animation videos of molecular vibration.

DC

  • Level of openness 3 ★★★
  • Document quality 2 ★★☆

An electronic state solver distributed with GAMESS, the quantum chemical (QM) calculation software. Combining energy density analysis and Divide-and-Conquer (DC) method, accurate QM calculation with electronic correlation is solved in a short time. Highly accurate QM calculations for many-atom/nano-scale material can be solved when run on a high performance super computer.

OACIS

  • Level of openness 3 ★★★
  • Document quality 2 ★★☆

An open-source framework for execution management of numerical simulation. By registering target simulators, information at the time of execution (parameters, date and time, hostname, version of simulators, etc.) and calculation results are saved automatically on database. Job submission and browse of job status can be performed efficiently from web browsers.

TRIQS/DFT tools

  • Level of openness 3 ★★★
  • Document quality 2 ★★☆

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.

VisBAR

  • Level of openness 3 ★★★
  • Document quality 2 ★★☆
A set of Python scripts for post-simulation data analysis of large-scale electronic state calculations. Currently the open script is ‘VisBAR Wave Batch’ that visualizes many wavefunctions, as isosurfaces, simultaneously. The script generates picture files in PNG and other formats from grid data files in the Gaussian cube format. Many data files can be treated in parallelism by MPI.
