I will discuss the derivation of second-order hydrodynamics from a projection operator techniques, which allows for obtaining the hydrodynamics equation in the strongly coupled regime and, at the same time, Kubo formulas for the relevant transport coefficients. I will then discuss the computation of the transport coefficients arising at the first order within the NJL model of quantum chromodynamics.

Solving Quantum Chromodynamics (QCD) at intermediate density and temperature is a long- standing open problem. Since the traditional methods don’t work in this region, even the precise phase structure of QCD is currently not known. The hot and dense part of the QCD phase diagram is probed in binary neutron star mergers. It is also conjectured to include a critical end point of the nuclear to quark matter transition whose location in the phase diagram will be narrowed down by upcoming heavy-ion experiments. The subject of the talk is the recently developed novel framework for the equation of state (EoS) of dense and hot QCD. This framework bridges the gap in theoretical predictions at intermediate densities by using the gauge/gravity duality, which maps the strongly coupled QCD to classical higher dimensional gravity. The model combines predictions from the gauge/gravity duality with input from lattice field theory, QCD perturbation theory and traditional nuclear theory methods.
