Query: Green's function formulation of quantum defect embedding theory   We present a Green's function formulation of the quantum defect embedding
theory (QDET) where a double counting scheme is rigorously derived within the
$G_0 W_0$ approximation. We then show the robustness of our methodology by
applying the theory with the newly derived scheme to several defects in
diamond. Additionally, we discuss a strategy to obtain converged results as a
function of the size and composition of the active space. Our results show that
QDET is a promising approach to investigate strongly correlated states of
defects in solids.
