We present a procedure that makes use of group theory to analyze and predict the main properties of the negatively charged nitrogen-vacancy (NV) center in diamond. We focus on the relatively low temperature limit where both the spin–spin and spin–orbit effects are important to consider. We demonstrate that group theory may be used to clarify several aspects of the NV structure, such as ordering of the singlets in the (e2) electronic configuration and the spin–spin and spin–orbit interactions in the (ae) electronic configuration. We also discuss how the optical selection rules and the response of the center to electric field can be used for spin–photon entanglement schemes. Our general formalism is applicable to a broad class of local defects in solids. The present results have important implications for applications in quantum information science and nanomagnetometry.

Continuous mode cooling and phonon routers for phononic quantum networks (2012, background): “The qubit states in the electronic ground state, which are highly immune against external perturbations, can be coupled via an optical Raman process involving an electronically excited state, which, in contrast, is strongly coupled to phonons [61].”
Measurement and Control of Single Nitrogen-Vacancy Center Spins above 600 K (2012, methodology): “The wavefunction of the (1)A1 state is a sum of two Slater determinants [22, 23]: ∣1A1 〉 = 1 √ 2 (|a1ā1exēx〉+ |a1ā1eyēy〉) .”

Isolated Spin Qubits in SiC with a High-Fidelity Infrared Spin-to-Photon Interface (2017, unknown): “We focus on these forms because a detailed theoretical treatment of this electronic structure, developed in the context of diamond NV centers, is already available in two recent works [52,53].”
First-principles theory of the luminescence lineshape for the triplet transition in diamond NV centres (2014, background): “Due to very similar atomic geometries of the (3)A2, (1)A1 and (1)E electronic states [11, 14, 15, 29] we suggest that the localized phonon mode found in our current study is the same as the one observed in the experiments of Kehayias et al.”
