Quantum Gravity

\[
\Box \phi + \gamma \partial^\mu \phi + \alpha \phi^3 + \beta \phi^5 = qE_{\text{Res}} + \lambda \langle \hat{Q} \rangle + \eta \epsilon^{\mu\nu\rho\sigma} \partial_\mu \phi \partial_\nu \phi \partial_\rho \phi \partial_\sigma \phi + \xi \zeta(x^\mu) + \kappa \partial_t \phi + \delta \phi E^2
\]

\begin{equation}
    G_{\beta\nu} + \beta \langle \phi^2 \rangle g_{\beta\nu} = 8\pi G (T_{\text{std}} + T_\phi)
\end{equation}

\begin{equation}
    \Box \phi = -\beta \phi - \beta \partial_t \phi + \beta \nabla^2 \phi + \beta \zeta R \phi
\end{equation}
