A VASP patch (VASP2mat ; vmat=10,11,12) is used to compute matrix representations of all the symmetries directly from the DFT calculations. Then, one can get the k⋅p parameters and Landé g-factors by the mat2kp code.

A VASP patch (VASP2mat ; vmat=13) is used to calculate the (spin) Berry curvature and (spin) Hall conductivity directly from the DFT calculations. Since the symmetry is used, only the k points in the irreducible Brillouin zone (IBZ) are computed.

A VASP patch (VASP2mat ; vmat=14) is used to compute the one-dimensional (1D) Wilson loops directly from the DFT calculations. One can calculate Wilson charge centers (WCC) for any given 1D k loops. By checking the evolution of the WCC, the band topology can be diagnosed from the ab initio calculations.

A VASP patch (VASP2mat ; vmat=13) is also used to calculate the dielectric constants directly from the DFT calculations. Since the symmetry is used, only the k points in the irreducible Brillouin zone (IBZ) are computed.
