diamond_nvm_gs.m

NV centre ground state spin system for diamond. Magnetic parameters are from S. Felton et al., Phys. Rev. B 79 (2009) 075203. Spin-lattice relaxation follows Eq. 1 in A. Jarmola et al., PRL 108 (2012) 197601. Electron spin T2 times are assumed to be T2=0.5*T1, as in the CPMG experiments reported in N. Bar-Gill et al., Nat. Comm. 4 (2013) 1743. Nuclear relaxation rates are informed guesses based on Pfender et al., Nat. Comm. 8 (2017) 834, and Soshenko et al., Quantum Electronics 51 (2021) 1144.
