Finite temperature dissipation and transport near quantum critical points

Abstract

I review a variety of model systems and their quantum critical points, motivated by recent experimental and theoretical developments. These are used to present a general discussion of the non-zero temperature crossovers in the vicinity of a quantum critical point. Insights are drawn from the exact solutions of quantum critical transport obtained from the AdS/CFT correspondence. I conclude with a discussion of the role of quantum criticality in the phase diagram of the cuprate superconductors. Contributed chapter to the book ‘Developments in Quantum Phase Transitions’, edited by Lincoln Carr.
