SumkDiscreteFromLattice.Recompute_Grid(n_points, method='Riemann', Q=None)[source]

(Re)compute the k-grid on the patch (or full BZ) given at construction.

Reallocates the grid arrays via SumkDiscrete.resize_arrays() and dispatches to the patch-based or full-BZ helper depending on whether patch is set.

Parameters:

n_pointsint: Number of grid points per spatial direction.
method{“Riemann”, “Gauss”}, optional: Integration scheme. Default "Riemann". The "Gauss" branch is not currently functional.
Qarray-like, optional: Momentum shift: when given, \(t(k + Q)\) is stored instead of \(t(k)\). Useful for evaluating quantities such as the bare susceptibility \(\chi_0(Q)\). Default None.
