z-Pares

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

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.

Z2Pack

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

Analytical tool to calculate the Z2 topological number or Chern number from given band structures, which are derived from first-principles calculations or tight-binding Hamiltonians. The topological numbers are calculated from the evolution of Wannier charge center and this method is applicable to the systems without inversion symmetries.

Zindaiji3

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

An application for visualization of large-scale many-particle simulation. This application can visualize information on a large number of particles treated in calculation of gravitational many-body problems, and provides many features for creating animations. It implements high-speed visualization with OpenGL, and supports graphical user interface (GUI) for operations.
