There has been a lot of work on quantum criticality and its CFT equivalence with AdS. Take a look at: String Theory, Quantum Phase Transitions and the Emergent Fermi-Liquid Authors: Mihailo Cubrovic, Jan Zaanen, Koenraad Schalm http://arxiv.org/abs/0904.1993 Another paper which is less conformal field related is Quantum Criticality in Heavy Fermion Metals Authors: Philipp Gegenwart, Qimiao Si, Frank Steglich (Submitted on 13 Dec 2007 (v1), last revised 31 Jan 2008 (this version, v2)) |
