13. For a ring of radius 50 nm, described in the TB model by 32 sites on the ring, and for J of the order of the hopping integral (w ≈ 5 meV) this condition is fulfilled at B < 200 T (the g-factor of GaAs has been considered).

27. This comes from the fact that the magnetic impurity is placed in the dot and acts like a small perturbation for the "ring" levels.
