  We study Randall-Sundrum brane models from the viewpoint of condensed
matter/quantum optics. Following the idea of analog gravity we obtain effective
metrics in fluid and Bose-Einstein-condensate systems mimicking those in the
brane framework. We find that the effect of warp factors in the bulk geometry
translates into finiteness of the analog systems. As an illustration of this
identification we give a new interpretation of the peculiar behaviour of the
critical temperature for the splitting of thick branes in warped spacetimes.
