Description
I will discuss a simple example of an AdS dual description of quantum Hall effect. More precisely, I discuss a U(1) gauge fields - complex scalar field theory in the background of a black hole in 3+1 dimensional anti-de Sitter space, as a dual description of a 2+1 dimensional system at a quantum Hall plateau. The model is inspired by the Zhang-Hansson-Karlhede effective theory, and by recent work on AdS duals of superconductivity.
