Holography and strongly coupled field theory with applications to condensed matter

The idea of Holography is that space, time and gravity is dual to a lower-dimensional Quantum Field Theory without gravity.

The idea of Holography is that space, time and gravity in D dimensions is dual to a D-1 dimensional Quantum Field Theory without gravity. In this way it provides a new perspective on how space, time and gravity emerge from quantum theory. Conversely, one can use such dualities as a way to study the otherwise inaccessible strongly coupled regimes of Quantum Field Theories.

As an example holography might be applicable in the study of strongly correlated electrons in two dimensions. This idea has been pursued with the purpose to formulate and study a string theory based model of graphene in a strong electromagnetic field as well as in an attempt to model a strongly correlated fractional topological insulator.
