AdS/CFT for the early stages of heavy ion collisions
I give a brief introduction to the AdS/CFT correspondence targeted at
heavy-ion physicists. I also review some insights to our understanding of the
early stages of heavy-ion collisions coming from selected studies made using
methods of the AdS/CFT correspondence.Comment: 8 pages, 4 figures. Plenary talk at the Quark Matter 2014 conferenc
QCD, diffraction and string theory
Recently, string theory on some specific curved backgroud spacetime
geometries has been conjectured to be equivalent to certain gauge theories
(AdS/CFT correspondence). This correspondence may be used to investigate the
non-perturbative regime of gauge theories. I describe its application to the
study of soft scattering amplitudes in a confining gauge theory. I describe two
qualitatively different applications: amplitudes with vacuum quantum number
exchange (Pomeron-like), amplitudes with Reggeon exchange. The last case
requires going beyond eikonal approximation on the gauge theory side.Comment: 5 pages. Presented at the 10th International Workshop on Deep

The emergence of noncommutative target space in noncritical string theory
We show how a noncommutative phase space appears in a natural way in
noncritical string theory, the noncommutative deformation parameter being the
string coupling.Comment: 21 pages, 1 figure. By mistake a wrong figure was included in v
