Easy-plane QED3's in the large Nf limit

We consider Quantum Electrodynamics in 2 + 1 dimensions with N-f fermionic or bosonic flavors, allowing for interactions that respect the global symmetry U(N-f/2)(2). There are four bosonic and four fermionic fixed points, which we analyze using the large N-f expansion. We systematically compute, at order O(1/N-f), the scaling dimensions of quadratic and quartic mesonic operators.We also consider Quantum Electrodynamics with minimal supersymmetry. In this case the large N-f scaling dimensions, extrapolated at N-f = 2, agree quite well with the scaling dimensions of a dual supersymmetric Gross-Neveu-Yukawa model. This provides a quantitative check of the conjectured duality.
