Title: The AdS/CFT correspondence -String Theory in the lab?

Abstract: The  Anti-de  Sitter/Conformal  Field  Theory  (AdS/CFT)  correspondence  is  one  of  the most  important  results  of  String  Theory.  It  states  that  a  gravity  theory  in  Anti-de Sitter space-time (AdS) is dual to a Conformal Quantum Field Theory on the boundary of  AdS.  The  duality  connects  strongly  coupled  Quantum  Field  Theories  to  weakly coupled  gravity  theories.  In  recent  years  it  has  been  suggested  that  this  fact  can  be used to gain easier access to strongly coupled Quantum Field Theories. Examples are real-time,  high  density  processes  in  Quantum  Chromodynamics  as  well  as  high temperature  superconductivity  which  is  presumably  driven  by  strong  interaction processes.  In  both  cases  experimental  data  exists  which  can  be  used  to  test  the correspondence.  In  this  talk  I  will  motivate  the  AdS/CFT  correspondence,  explain  its potential and point out future directions.
