The gauge/gravity duality has proven to be a very useful tool in the understanding of quantum field theories outside the perturbative regime. In particular, holography has been able to shed light not ...

AdS/CFT correspondence combines ideas of holography and duality in a way that allows one to make calculations in the otherwise hardly accessible (strongly coupled) regime of the target theory. In this ...
