Easy-plane QED$_3$'s in the large $N_f$ limit

Understand

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.
