For Bloch electrons, the Berry connection is defined as $$ \mathcal{A}_n(\mathbf{k}) = i\langle u_{n\mathbf{k}}|\partial_\mathbf{k}|u_{n\mathbf{k}}\rangle \tag{1} $$ where $u_{n\mathbf{k}}$ is the cell-periodic part of the Bloch function with band index $n$ and crystal momentum $\mathbf{k}$. As f...
