SumkDiscreteFromLattice.Recompute_Grid(n_points, method='Riemann', Q=None)

(Re)Computes the grid on the patch given at construction:

• n_points: Number of points in the BZ in EACH direction

• method: Riemann (default) or ‘Gauss’ (not checked)

• Q: anything from which a 1d-array can be computed.

  computes t(k+Q) instead of t(k) (useful for bare chi_0)
