I classify the phases as gapped, conformal, or compressible quantum matter. Gapped quantum matter is illustrated by a simple discussion of the $Z_{2}$ spin liquid, and connections are made to topological ﬁeld theories. I discuss how conformal matter is realized at quantum critical points of realistic lattice models, and make connections to a number of experimental systems. Recent progress in our understanding of compressible quantum phases which are not Fermi liquids is summarized. Finally, I discuss how the strongly-coupled phases of quantum matter may be described by gauge-gravity duality. The structure of the $Nc \rightarrow \infty$ limit of $SU(N_c)$ gauge theory, coupled to adjoint fermion matter at non-zero density, suggests aspects of gravitational duals of compressible quantum matter. en_US dc.description.sponsorship Physics en_US dc.language.iso en_US en_US dc.publisher World Scientific Publishing en_US dc.relation.hasversion http://arxiv.org/abs/1203.4565 en_US dash.license OAP dc.subject high energy physics en_US dc.subject quantum physics en_US dc.title The Quantum Phases of Matter en_US dc.type Conference Paper en_US dc.description.version Accepted Manuscript en_US dash.depositing.author Sachdev, Subir dc.date.available 2013-07-25T18:31:06Z dc.relation.book The Theory of the Quantum World Proceedings of the 25th Solvay Conference on Physics en_US dash.contributor.affiliated Sachdev, Subir
