  1. Lattice Vector

    Linked via "real space"

    Relationship to Reciprocal Space
    Lattice vectors exist in real space$(\mathbf{r}\text{-space})$, but their structure is intrinsically linked to the reciprocal lattice vectors $(\mathbf{k}\text{-space})$. The relationship is defined by the orthogonality condition:
    $$\mathbf{k} \cdot \mathbf{r} = 2\pi n$$
