Description
Holography has proved to be a useful tool to study strongly
coupled plasmas, similar to the quark gluon plasma created
in heavy ion collision experiments. Moreover, recently a new
approach has shown that it could be used to study the
initial stage of these collisions as well. In this regard,
it remains to be seen how close the holographic studies will
actually be to the experimental observations, since
holographic setups do not describe QCD directly. This talk
will consist of a review on how a collision of gravitational
shockwaves in an AdS spacetime can model a heavy ion
collision, together with a sketch of the numerical
techniques involved in the calculation. Finally, I will also
comment on the introduction of transverse inhomogeneities
that may give a more accurate approach to real world collisions.
