SUMMARY:Holographic Superconductors - Julian Sonner (Imperial)
DTSTART:20090528T120000Z

CONTACT:Diego Hernan Correa
DESCRIPTION:The geometric properties of charged\, asymptotically AdS black
  holes make it possible for charged scalar fields to condense if the tempe
 rature of the black hole is sufficiently low. A non-zero expectation value
  of such a field spontaneously breaks the gauge symmetry. This gravitation
 al version of the abelian Higgs effect has recently been interpreted as be
 ing dual to a boundary superconductor transition. In this talk I want to d
 escribe certain aspects of the phenomenology of these 'holographic superco
 nductors'\, focusing in particular on effects related to rotation. In such
  cases the emergence\nof a magnetic field is expected in the  superconduct
 ing state\, and indeed I will show how this so-called London field is desc
 ribed in the gravitational setting.\n
