Journal of High Energy Physics 2013, no. 9: 127.1029-8479http://nrs.harvard.edu/urn-3:HUL.InstRepos:12220377In 2 + 1-dimensional conformal field theories with a global U(1) symmetry, monopoles can be introduced through a background gauge field that couples to the U(1) conserved current. We use the state-operator correspondence to calculate scaling dimensions of such monopole insertions. We obtain the next-to-leading term in the 1/Nb expansion of the Wilson-Fisher fixed point in the theory of Nb complex bosons.en-USSolitons Monopoles and InstantonsField Theories in Higher DimensionsGlobal SymmetriesJournal Article2014-05-2810.1007/jhep09(2013)127
