WebJun 17, 2024 · The NV center spin in the diamond lattice undergoes a variety of interactions because of external magnetic and electric fields, … The Hamiltonian, a quantum mechanical equation describing the dynamics of a system, which shows the influence of different factors on the NV center can be found below. Although it can be challenging, all of these effects are measurable, making the NV center a perfect candidate for a quantum sensor. … See more The nitrogen-vacancy center (N-V center or NV center) is one of numerous point defects in diamond. Its most explored and useful property is its photoluminescence, which allows observers to read out its spin-state. The NV … See more Nitrogen-vacancy centers are typically produced from single substitutional nitrogen centers (called C or P1 centers in diamond literature) by irradiation followed by annealing at … See more The NV center has a ground-state triplet ( A), an excited-state triplet ( E) and two intermediate-state singlets ( A and E). Both A and E … See more Optical spin manipulation Optical transitions must preserve the total spin and occur only between levels of the same total spin. … See more The nitrogen-vacancy center is a point defect in the diamond lattice. It consists of a nearest-neighbor pair of a nitrogen atom, which substitutes for a carbon atom, and a lattice vacancy. Two charge states of this defect, neutral NV and negative … See more NV centers emit bright red light ( E→ A transitions), if excited off-resonantly by visible green light ( A → E transitions). This can be done … See more The spectral shape and intensity of the optical signals from the NV centers are sensitive to external perturbation, such as temperature, strain, electric and magnetic field. However, the use of spectral shape for sensing those perturbation is impractical, as the … See more
