The so-called gauge/gravity duality provides a link between gravitational and quantum physics, more specifically between quantities in an asymptotic Anti-de Sitter spacetime and its dual conformal field theory on the boundary (AdS/CFT correspondence). The duality can be used to obtain observables in a strongly coupled system by addressing the analogous problem in the associated weakly curved gravitational theory.
This correpondence turned out to be a successful means to calculate transport coefficients of (non-)conformal field theories, which for example lead to a prediction of the low shear viscosity over entropy density ratio later measured in heavy ion collisions. Near equilibrium quantities are typically derived from perturbations of static gravitational background geometries. In order to study far from equilibrium properties on the field theory side, we work with a generalized time-dependent Vaidya background on the gravity side: A black brane which grows due to the collapse of infalling null matter in the presence of electromagnetic fields. This can find application, e.g., in the description of heavy ion collisions.
