Quantum criticality of U(1) gauge theories with fermionic and bosonic matter in two spatial dimensions.

The quantum phase transition between the Higgs and Coulomb phases is described by a conformal field theory (CFT). At large $N_b$ and $N_f$, but for arbitrary values of the ratio $N_b∕N_f$, we present computations of various critical exponents and universal amplitudes for these CFTs. We make contact with the different spin liquids, charge liquids, and deconfined critical points of quantum magnets that these field theories describe. We compute physical observables that may be measured in experiments or numerical simulations of insulating and doped quantum magnets. en_US dc.description.sponsorship Physics en_US dc.language.iso en_US en_US dc.publisher American Physical Society en_US dc.relation.isversionof doi://10.1103/PhysRevB.77.155105 en_US dc.relation.hasversion http://arxiv.org/abs/0801.0723v2 en_US dash.license OAP dc.subject strongly correlated electrons en_US dc.title Quantum Criticality of U(1) Gauge Theories with Fermionic and Bosonic Matter in Two Spatial Dimensions en_US dc.type Journal Article en_US dc.description.version Author's Original en_US dc.relation.journal Physical Review B en_US dash.depositing.author Sachdev, Subir dc.date.available 2012-01-10T19:04:24Z dc.identifier.doi 10.1103/PhysRevB.77.155105 * dash.contributor.affiliated Sachdev, Subir
