We study the correlation functions of Coulomb branch operators four-dimensional $\mathcal{N} = 2$ Superconformal Field Theories (SCFTs). focus on rank-one theories, such as SU(2) gauge theory with four fundamental hypermultiplets. "Extremal" functions, involving exactly one anti-chiral operator, are perhaps simplest nontrivial in Quantum Theory. show that large charge limit extremal correlators...
