Query: Holographic Superfluids and Superconductors in Dilaton-Gravity   We investigate holographic models of superfluids and superconductors in which
the gravitational theory includes a dilatonic field. Dilaton extensions are
interesting as they allow us to obtain a better description of low temperature
condensed matter systems. We focus on asymptotically AdS black hole
configurations, which are dual to field theories with conformal ultraviolet
behavior. A nonvanishing value of the dilaton breaks scale invariance in the
infrared and is therefore compatible with the normal phase being insulating (or
a solid in the fluid mechanical interpretation); indeed we find that this is
the case at low temperatures and if one appropriately chooses the parameters of
the model. Not only the superfluid phase transitions, but also the response to
external gauge fields is analyzed. This allows us to study, among other things,
the vortex phase and to show that these holographic superconductors are also of
Type II. However, at low temperatures they can behave in a qualitatively
different way compared to their analogues without the dilaton: the critical
magnetic fields and the penetration depth can remain finite in the small T/T_c
limit.
