- class netket.graph.Pyrochlore#
Constructs a pyrochlore lattice of a given spatial extent. Periodic boundary conditions can also be imposed.
Sites are returned at the 16c Wyckoff positions of the FCC lattice (/8, [1 -1 -1]/8, [-1 1 -1]/8, [-1 -1 1]/8, and translations thereof).
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 a pyrochlore lattice with 3×3×3 primitive unit cells:
>>> from netket.graph import Pyrochlore >>> g = Pyrochlore(extent=[3,3,3]) >>> print(g.n_nodes) 108
