An external periodic field is able to change the asymptotic values of the populations of two asymmetric energy levels in a bistable potential tending to equalize the populations of the discrete levels, or even to reverse the populations for space-extended systems. The population of the oscillating well can either decrease or increase compared with the field-free case, depending on the frequency of the external field.
