Final Report Summary - UNIFY (Unification of Fundamental Forces and Applications)
During four years, research at the UNIFY network has been performed along three main research lines. These include the work package on the gauge/gravity duality, the work package on cosmology and numerical relativity, and the work package on string theory, supergravity, quantum gravity and black hole physics.
The above subjects have been intensively studied, with many new results, which include: new developments towards our goal of solving N=4 SYM in the planar limit, including the spectrum, correlation functions and amplitudes of this theory; new applications of the gauge/gravity duality to describe QCD and other strongly correlated systems; improvement of our description of cosmological singularities, as well as of alternative explanations on the nature of dark matter and dark energy; the development of numerical relativity techniques that will be invaluable to understand gravitational waves emitted in violent Astrophysical phenomena; new explorations in string theory, in particular new studies in black hole physics, quantum gravity and particle physics; the exploration of other alternative roots for a theory of quantum gravity, beyond string theory; the revival of the bootstrap programme for Conformal Field Theories.
Future progresses in the above venues of research are likely to change and shape our views and understandings of physical phenomena such as: the physics of the strong interaction; the nature of the big bang singularity and of the present acceleration of our Universe; the violent Universe that will be uncovered by future gravitational waves detection; the physics behind unifying theories that ought to include strong gravitational fields. The UNIFY network contributed to a considerable improvement in our current views on the above key issues, which will most likely have an impact in current view points of our Universe.
