The epsilon expansion meets semiclassics
Abstract We study the scaling dimension Δ ϕ n $$ {\Delta}_{\phi^n} $$ of the operator 𝜙 n where 𝜙 is the fundamental complex field of the U(1) model at the Wilson-Fisher fixed point in d = 4 − ε. Even for a perturbatively small fixed point coupling λ ∗, standard perturbation theory breaks down for s...
