translational_symmetry

translational_symmetry(a1: bool | float = True, a2: bool | float = True, a3: bool | float = True) → TranslationalSymmetry

Simple translational symmetry in, the form of \(e^{i \vec k \cdot \vec r}\).

Parameters:

a1, a2, a3bool or float

Control translation in the ‘a1, a2, a3’ lattice vector directions. Possible values:

• False -> No translational symmetry in this direction.

• True -> Translation length is automatically set to the unit cell length.

• float value -> Manually set the translation length in nanometers.
