Title: Bootstrapping mixed correlators in three-dimensional cubic theories

Abstract

Three-dimensional theories with cubic symmetry are reported on using themachinery of the numerical conformal bootstrap. Crossing symmetry andunitarity are imposed on a set of mixed correlators, and various aspectsof the parameter space are probed for consistency. An isolated allowedregion in parameter space is found under certain assumptions involvingpushing operator dimensions above marginality, indicating the existenceof a conformal field theory in this region. The obtained results havepossible applications for ferromagnetic phase transitions as well asstructural phase transitions in crystals. They are in tension with previous ε expansion results, as noticed already in earlier work.
