quantax.sites.TriangularB

class quantax.sites.TriangularB(extent: int, boundary: int | Sequence[int] = 1, particle_type: PARTICLE_TYPE | str = PARTICLE_TYPE.spin, Nparticles: None | int | Tuple[int, int] = None, double_occ: bool | None = None)

2D triangular lattice type B. See PhysRevB.47.5861 Fig.1 N=12 as an example. The total number of particles is given by \(N = 3 \times \mathrm{extent} ^ 2\).
