Hamiltonian of nv center
Webdependence of the NV center’s luminescence, together with a nearby microwave antenna, allow us to perform optically de-tected ESR measurements with simultaneous three-dimensional control in solution. We develop a model of the observed ESR spectra based on the ground-state Hamiltonian that accounts for the random motion of NV centers in the ...

WebFor NV center–based EPR, the DEER sequence is widely used for the detection of electron spins (5–7, 9, 10), where the NV center itself is also an electron spin (S = 1). Because of … 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).
