First, I will summarize recent insights about how global and gravitational anomalies can affect experiments, such as heavy ion collisions, quantum quenches in condensed matter systems, or data from astrophysical sources. To give a concrete example: a chiral anomaly leads to a transport effect called chiral vortical effect. This effect appears at the same order in the hydrodynamic gradient expansion as, for example, electric conductivity or shear viscosity. In order to understand how such anomalous transport effects will appear in experiments, we need to understand the dynamics of strongly coupled systems near and far-from equilibrium. As the two essential tools we will use:
(i) the fluid/gravity correspondence, and then more general fully-time dependent holographic models derived from string theory, in parallel with
(ii) effective field theories, for example, relativistic hydrodynamics.
