Abstract
We find that for a one-dimensional condensate in the presence of an applied ac field, a significant absorption peak should occur for values of the external frequency just below the pinning frequency ωF. This power absorption is due to those nonlinear normal modes of the condensate known as "breathers," which are shown to phase lock with the applied field.
