Description
We use gauge/string duality to model a heavy ion collision in a non-conformal
gauge theory. We focus on new physics (as compared to the conformal case)
such as the non-trivial equation of state and the presence of a non-zero bulk
viscosity. We study the effect of this non-conformality on the
hydrodynamization of the system.
The gravity model consists of solving numerically the collision of
shock-waves with a non-trivial scalar field. We adjust the scalar field
potential such that the bulk space-time coincides with AdS in the infrared and
in the ultraviolet with different AdS radius. This introduces a non-trivial
running of the dual gauge theory coupling constant which we choose at our
convenience.
