Abstract

In this paper a general study of nitrogen-vacancy center internal state in diamond is presented. This study is based on experimental and theoretical findings found in literature. First, a Hamiltonian model for center nitrogen-vacancy internal state is proposed in terms of a complete set of commuting observables (CSCO), which consist of angular momentum (Formula Presented), spin momentum Ŝ, total angular momentum Ĵ = (Formula Presented) + Ŝ, and spin momentum on z-direction Ŝz. The second quantization formalism –in steady-state (conservative model)– is used. The creation and annihilation operators are used to described the steady spin-levels structure and in dynamic-state (non-conservative model) and can also describe the system dynamic between different spin-levels transitions. Finally, a discussion is presented about the application of this study in the photochromism phenomenon and solid-state quantum bit (qubit).
