Critical phenomena, like phase transitions, are essentially defined by fractal like properties. Scale invariance in systems near a phase transition inspired the technique now called renormalization group. It remains a central tool in statistical physics, but isn't really in vogue at the moment. Kenneth Wilson won a Nobel prize in 1982 for his work on RG. [1] https://en.wikipedia.org/wiki/Renormalization_group https://en.wikipedia.org/wiki/Renormalization_group
