Physical Review B 88, no. 15: 155109.1098-01211550-235Xhttp://nrs.harvard.edu/urn-3:HUL.InstRepos:12220674We compute current correlators of the CPN−1 field theory in 2+1 dimensions, both at the critical point and in the phase with spontaneously broken SU(N) symmetry. Universal constants are obtained to next-to-leading order in the 1/N expansion. Implications are noted for quantum critical points of antiferromagnets and their vicinity.en-USJournal Article2014-05-2810.1103/physrevb.88.155109
