SumkDiscreteFromLattice
(lattice, patch=None, n_points=8, method='Riemann')[source] - Computes
\[G \leftarrow \sum_k (\omega + \mu - \epsilon_k - \Sigma(k,\omega))^{-1}\]for GF functions with blocks of the size of the matrix eps_k with a discrete sum.
- The object contains the discretized hoppings and points in the arrays hopping, bz_points,bz_weights,mu_pattern,overlap (IF non orthogonal) It can also generate a grid (ReComputeGrid) for a regular grid or a Gauss-Legendre sum for the whole Brillouin Zone or a patch of the BZ.
Methods
Recompute_Grid (n_points[, method, Q]) |
(Re)Computes the grid on the patch given at construction: | ||
__init__ (lattice[, patch, n_points, method]) |
|
||
n_kpts () |
Returns the number of k points | ||
resize_arrays (nk) |
Just constructs the arrays, but without initializing them - nk: total number of k points |
Attributes
GFBlocIndices |
Returns the ONLY block indices accepted for the G and Sigma argument of the SumK function |
