A bstract In this work, we initiate a positive semi-definite numerical bootstrap program for multi-point correlators. Considering six-point functions of operators on a line, we reformulate …
A bstract In this paper we consider classical and quantum versions of the critical long-range O (N) model, for which we study finite-size and finite-temperature effects, respectively, at …
Quantum long-range models at zero temperature can be described by fractional Lifshitz field theories, that is, anisotropic models whose actions are short range in time and long range in …
Dimensional correspondences have a long history in critical phenomena. Here, we review the effective dimension approach, which relates the scaling exponents of a critical system in …

We show that by imposing the conformal Wald identity, one can extract conformal data of the corresponding short-range/local CFT from the long-range perturbation theory. We first apply …
We correct the computation of one Feynman diagram in the three-loop beta functions for the long-range quartic multi-scalar model, originally presented in (2020 J. Phys. A: Math. Theor …

We derive a manifestly superconformal expression for the leading-order two-point functions of all single trace chiral primary operators in 4d N= 4 super-Yang-Mills theory with a co …
We investigate the quantum forces occurring between the defects and/or boundaries of a conformal field theory (CFT). We propose to model imperfect defects and boundaries as …

We study the conformality loss of theories with long-range interactions. We consider the $ O (2)\times O (N) $ multiscalar model with coupling $ r^{-d-\delta} $ in $ d= 4-\epsilon …
