DESCRIPTION:The promise of the present flirtation between string theory an
 d condensed matter physics is that the former will finally demonstrate emp
 irical relevance by shedding light on the great mysteries of the latter. T
 he holy grail problem in condensed matter has been since 25 years the mech
 anism of superconductivity at a high temperature. On the other hand\, the 
 first substantial result produced by the AdS/CFT correspondence in this co
 ntext is the discovery of holographic superconductivity by Gubser and Hart
 noll-Herzog-Horowitz in 2008. This demonstrates that the superradiance ins
 tability of an AdS Reissner-Nordstrom black hole in the presence of a scal
 ar field dualizes in the statement that a strongly interacting conformal f
 ield theory at a finite density has a superconducting instability that bea
 rs similarities to the standard BCS mechanism while it is yet very differe
 nt. I will present and explain the design of an experiment that is practic
 al enough to be realized in the experimental laboratory\, being taylored t
 o observe the qualitative differences between the BCS and the holographic 
 mechanisms [1].  \n\n[1] J.-H. She et al.\, Phys. Rev. B 84\, 144257 (2011
