The AdS/CFT correspondence offers a very interesting connection between string theory and conformal field theories allowing for an intriguing weak/strong duality. String theory, originally invented to explain the strong force found in nuclei, has undergone tremendous transformations to be promoted as an promising candidate for the unifications of all fundamental forces. As a "spin-off" it deepened our understanding of quantum field theories and gave rise to new mathematics, which in turn inspired physicist to tackle the long standing problems of going beyond perturbative descriptions, desperately needed to describe strongly coupled systems. Apart from the more fundamental AdS/CFT correspondence, a generalized version called gauge/gravity duality has shown great potential to explore strongly correlated many-body quantum systems in condensed matter physics. In particular, there are various approaches to understand quantum critical phases, conformal matter and (high Tc) superconductivity. In this talk a general introduction to the AdS/CFT correspondence will be given, explaining the crucial ingredients originating from string theory as well as the connection to the seemingly generic feature of gravity, the so called holographic principle.
