We consider the Schrödinger operator −Δ + V on ℝn with n ≥ 3 and V a member of the reverse Hölder class ℬs for some s > n/2. We obtain the boundedness of the second order Riesz transform ∇2 (−Δ + V)−1 on the weighted spaces Lp(w) where w belongs to a class of weights related to V. To prove this, we develop a good-λ inequality adapted to this setting along with some new heat kernel estimates.
