\subsection{Noether Theorem and Conservation}
Starting point: $a_\mathbf{k}^\dagger$ should also increase the momentum of the system by $\hbar \mathrm{k}$.
\subsubsection{Transformation and Symmetry}
\begin{enumerate}
\item Lorentz transform:
$$x^\mu \rightarrow \Lambda^\mu_{\, \nu}x^\nu$$
\end{enumerate}
