Let's consider a displacement by $L$ in the $x$-direction $$ -\mathbf{\delta r}(\mathbf{r} + L\mathbf{\hat{x}}) &= \mathbf{\delta r}(\mathbf{r}) +\mathbf{\delta r}(\mathbf{r} + L\mathbf{\hat{x}}) = \mathbf{\delta r}(\mathbf{r}) $$ To satisfy this equation, we arrive at the condition $k_x=p 2 \pi/L$]$, with $p= ..., -2, -1, 0, 1, 2$ in $\mathbb{Z}$. -- GitLab
