Bravais Lattice

class triqs.lattice.tight_binding.BravaisLattice

Bravais Lattice with given unit vectors and atomic positions

Parameters:

• units (numpy.ndarray of float, shape=(d,d), 1<=d<=3) – Matrix with unit vectors of the Bravais Lattice as rows

• atom_orb_pos (list of three-vectors of float, optional) – The atomic orbital positions within the unit cell. Defaults to [(0,0,0)]

• atom_orb_name (list of str, optional) – The atomic orbital names. Defaults to list of empty strings.
