Abstract
The spin Hamiltonian method in combination with ab initio calculations of the spin characteristics of quantum registers that include an electron spin S = 1 of a single NV center in the ground electronic state and nuclear spins I = 1/2 of several atoms 13C located at different lattice sites near the vacancy of the NV center is applied to find eigenvalues and eigenfunctions of spin systems NV + n 13C for cases where the lattice sites nearest to the vacancy of the NV center contain one, two, or three 13C nuclear spins, as well as for cases where 13C atoms are located at sites more distant from the vacancy. For these single spin NV + n 13C systems, the spectra of optically detected magnetic resonance (ODMR) are calculated, which agree well with available experimental data.
