WebbThus, in the presence of an electric field, the energies of states 1 and 2 are shifted upwards and downwards, respectively, by an amount . These states are orthogonal linear combinations of the original and states. Note that the energy shifts are linear in the electric field-strength, so this effect--which is known as the linear Stark effect ... Webbto the vacancy.16 In this Hamiltonian, ˚= 0 is de ned as being along the projection of one of the vacancy-carbon axes on the transversal plane. For the lower transition, the shift is positive at ˚ B = ˚ E = 0, where both elds are in the direction of a carbon atom. Hence, the shift follows the three-fold symmetry of the NV, as ˚= ˚ B ...
