property Lattice.reciprocal¶

Reciprocal lattice.

The reciprocal lattice to a given lattice with dimension \(d\) and lattice vectors \(\boldsymbol a_i\) for \(i \in \{1, \dots, d\}\) is defined by lattice vectors \(\boldsymbol b_j\) with \(j \in \{1, \dots, d\}\) such that \(\boldsymbol a_i \boldsymbol b_j = 2 \pi \delta_{ij}\) is fulfilled.
