Anomalous Dimensions at Large Charge in \(d=4\ \mathrm {O}(N)\) Theory
Recently it was shown that the scaling dimension of the operator $\phi^n$ n in $\lambda(\bar{\phi}\phi)^2$ theory may be computed semiclassically at the Wilson–Fisher fixed point in $d = 4 -e$, for generic values of λn, and this was verified to two-loop order in perturbation theory at leading and su...
