      abstract     = {We study conformal field theories with finite group
                      symmetries with spontaneous symmetry breaking (SSB) phases
                      which persist at all temperatures. We work with two λϕ$^4$
                      theories coupled through their mass terms. The two λϕ$^4$
                      theories are chosen to preserve either the cubic symmetry
                      group, or the tetrahedral symmetry group. A one-loop
                      calculation in the 4 $-$ ϵ expansion shows that there exist
                      infinitely many fixed points that can host an all
                      temperature SSB phase. An analysis of the renormalization
                      group (RG) stability matrix of these fixed points, reveals
                      that their spectrum contains at least three relevant
                      operators. In other words, these fixed points are
                      tetracritical points.},
