triqs.lattice.tight_binding.TBLattice.hoppings

property TBLattice.hoppings

Real-space hoppings as a {displacement: matrix} dict.

Each key is a tuple of integers giving a real-space displacement in multiples of the lattice basis vectors; the corresponding value is the hopping matrix between orbitals at that displacement.

Returns:

dict

Mapping from displacement tuples to numpy.ndarray hopping matrices of shape (n_orbitals, n_orbitals).
