摘要：

Using both the second-order correction of perturbation theory and the exact computation due to Dalgarno-Lewis, we compute the second-order noncommutative Stark effect, i.e., shifts in the ground-state energy of the hydrogen atom in the noncommutative space in an external electric field. As a side result we also obtain a sum rule for the mean oscillator strength. The energy shift at the lowest order is quadratic in both the electric field and the noncommutative parameter theta. As a result of noncommutative effects the total polarizability of the ground state is no longer diagonal.
