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.

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.
