The gauge gravity duality and its applications to real world strongly coupled systems

Final Report Summary - ADSCFT MUNICH (The gauge gravity duality and its applications to real world strongly coupled systems)

The Marie Curie project AdSCFT Munich as part of FP7-MC-IEF has now completed its planned two-year period with important new results on applying the AdS/CFT correspondence, a new development in theoretical physics originating from string theory, to systems of relevance in heavy-ion and condensed matter physics. The fellow Dr. Jonathan Shock has worked at the Max Planck Institute for Physics in Munich within the research group of Dr. Johanna Erdmenger. He has published four papers in the Journal of High Energy Physics (JHEP), the leading journal in this research area, on the subjects outlined in the formal proposal, thus achieving the proposed milestones. He has also spent time in many other research institutes and universities within the EU and in China, disseminating these results, gaining new expertise and bringing it back to Munich. He has also taken part in outreach programs both within the EU and outside and this has allowed him to get strong ties with teaching institutions around the world. These will continue to impact his career development for the foreseeable future. During the two years the fellow has also expanded his areas of interest thanks to the career advancement opportunities of the Marie Curie fellowship. This has resulted in him winning a faculty position as a lecturer in the department of Mathematics and Applied Mathematics at the University of Cape Town in South Africa. It is certainly in large part thanks to the Marie Curie fellowship that the fellow was awarded this prestigious position.

The research undertaken has encompassed formal aspects of the AdS/CFT correspondence, as well as applications to heavy-ion physics (in particular early states close to thermalisation) and condensed matter physics (in particular superconductivity). The four published articles are outlined below:

The open string membrane paradigm with external electromagnetic fields
Keun-Young Kim, Jonathan Shock, Javier Tarrio - JHEP 06 (2011) 017

In this paper the fellow and collaborators were able to develop an entirely new paradigm for understanding regions of D-branes in the presence of electric fields which previously had not been understood. By developing an open string membrane paradigm the fellow was able to show that an effective horizon develops on a D-brane when large electric fields are present. Using this new membrane paradigm it is possible to find, in a very simple manner, transport properties of gauge theories when electric and magnetic fields are turned on. Such behaviour is extremely important now as this can be applied both to the heavy ion collision physics at the LHC as well as to lower dimensional condensed matter systems which are being studied in great detail via the holographic correspondence.
