- class netket.graph.FCC#
Constructs an FCC lattice of a given spatial extent. Periodic boundary conditions can also be imposed Sites are returned at the Bravais lattice points.
int]) – Number of primitive unit cells along each direction, needs to be an array of length 3
bool]]) – If True, the lattice will have periodic boundary conditions (PBC); if False, the lattice will have open boundary conditions (OBC). This parameter can also be a list of booleans with same length as the parameter length, in which case each dimension will have PBC/OBC depending on the corresponding entry of pbc.
kwargs – Additional keyword arguments are passed on to the constructor of netket.graph.Lattice.
- Return type:
Construct an FCC lattice with 3×3×3 primitive unit cells:
>>> from netket.graph import FCC >>> g = FCC(extent=[3,3,3]) >>> print(g.n_nodes) 27
