triqs.gf.meshes.MeshBrZone

class triqs.gf.meshes.MeshBrZone

Momentum mesh on a BrillouinZone)

The unit vectors $U$ of the mesh are constructed such that

$$K = N * U$$

where $K$ is the reciprocal matrix and $N$ the periodization matrix.

Parameters (Option 1)

bzBrillouinZone

The underlying Brillouin Zone

dimsnumpy.ndarray of integers, shape=(3,)

The extent of each dimension

Parameters (Option 2)

bzBrillouinZone

The underlying Brillouin Zone

n_kint

Number of mesh-points in each reciprocal direction
