Description
Wilson introduced the concept of the renormalization group to statistical physics, providing a universal understanding of critical phenomena. According to this framework, it is generally believed that scale invariance at the critical point leads to the emergence of conformal invariance. However, there exist materials in nature, such as the ferromagnet EuS, that exhibit scale symmetry but lack conformal symmetry at criticality. In this talk, I will explain the mechanism behind this peculiar property. Furthermore, I will present non-perturbative results concerning these systems.
