Abstract Scalar field theories with quartic interactions are of central interest in the study of second-order phase transitions. For three-dimensional theories, numerous studies make use of the fixed-dimensional perturbative computation of [B. Nickel

Abstract In theories with renormalons the perturbative series is factorially divergent even after restricting to a given order in 1/N, making the 1/N expansion a natural testing ground for the theory of resurgence. We study in detail the interplay be

Abstract In the classically unbroken phase, 3d O(N) symmetric ϕ 4 vector models admit two equivalent descriptions connected by a strong-weak duality closely related to the one found by Chang and Magruder long ago. We determine the exact analytic ren

In theories with renormalons the perturbative series is factorially divergent even after restricting to a given order in $1/N$, making the $1/N$ expansion a natural testing ground for the theory of resurgence. We study in detail the interplay between

Renormalization group (RG) and resummation techniques have been used in $N$-component ${\ensuremath{\phi}}^{4}$ theories at fixed dimensions below four to determine the presence of nontrivial IR fixed points and to compute the associated critical pro
