Résumé |
Despite the many successes of holography during the past two decades, we face several challenges in connecting its predictions with measurable experiments. Most formidable is establishing a bulk dual to non-supersymmetric Yang-Mills theory. We must also further develop our formalism for performing calculations at finite N and finite coupling strength. In this talk, I will discuss recent progress in addressing the latter of these problems. Namely, I will present new holographic results for the behaviour of coupling-dependent properties of hydrodynamics, thermalisation and higher-energy spectrum, as well as physics far from equilibrium in a model of heavy ion collisions. By analysing higher-derivative bulk theories, I will argue that in holography, coupling-dependent properties of the spectrum and transport transition to those expected from weakly coupling quantum field theory at a remarkably fast rate. |
