Understanding hydrodynamization in microscopic models of heavy-ion collisions has been an important topic in current research. Many lessons obtained within the strongly-coupled (holographic) models originate from the properties of transient excitations of equilibrium encapsulated by short-lived quasinormal modes of black holes. The aim of this talk is to develop similar intuition for expanding...

We revisit the calculation of long time tails in non-relativistic fluid dynamics. We show how to compute long time tails and bounds on transport coefficients in the shear, bulk, and thermal diffusivity channel. We study the constraints from scale invariance, and we show how the calculations can be extended to account for critical behavior.

I will talk about relativistic thermodynamics and magneto-hydrodynamics, with an emphasis on the derivative expansion, the transport coefficients, and the Kubo formulas.

Non-perturbative techniques are needed to study strongly coupled systems. One powerful approach is the n-particle irreducible effective action. The technique provides a systematic expansion for which the truncation occurs at the level of the action. However, renormalisation using a standard counterterm approach is not well understood. At the 2PI level one must introduce multiple counterterms,...

We discuss recent developments in the semiholographic model for heavy ion collisions (HICs) proposed by Iancu and Mukhopadhyay and further developed by Mukhopadhyay, FP, Rebhan, and Stricker. In this approach a GLASMA description of the early stages of HICs, i.e. a classical Yang-Mills field theory is coupled to a holographic model which plays the role of a bath of strongly coupled gluons. We...

Ever since the discovery of the quark-Gluon plasma (QGP) the location of the critical point in the QCD phase diagram - the end point of the first-order transition between hadron matter and QGP - has been a main research goal for heavy-ion collisions experiments. We use the gauge/gravity duality to study as first a four-dimensional, strongly-coupled gauge theory with a first-order thermal phase...
