Phase transition in the holographic model of superfluidity with   backreactions
  In the fully back reacted geometry we develop a supercurrent solution which corresponds to a deformation of superconducting black holes by the spatial component of gauge fields with a non- trivial radial dependence. We investigate the influence of the backreaction on the condensation and the phase structure in the AdS black hole spacetime. Different from that observed in the probe limit, we find that two operators cannot give consistent information on the phase diagram. We argue that only one of these two operators can reflect the real property of the condensation and phase structure in the holographic superconductor. We also generalize our study to the associated phase diagram in the AdS soliton background.
