Based on string theory, gauge/gravity duality maps strongly coupled quantum field theories to weakly coupled gravity theories. It thus provides a new approach for studying physical phenomena in strongly coupled systems. We describe the main features of this approach and discuss selected examples. These include new results for relativistic hydrodynamics and for anomalous transport, with possible implications for Dirac matter and for Weyl semimetals. As a further example, we present a new Kondo model within gauge/gravity duality, which amounts to a Luttinger liquid coupled to a magnetic impurity.
