SQCD, Superconducting Gaps and Cyclic RG Flows
arXiv:1202.4306
Abstract
We consider the relation between the Ω-deformed N=2 SQCD with the single deformation parameter and integrable models of the BCS-like superconductivity. It is argued that the vortex string worldsheet theory is related to the Russian Doll(RD) model of the truncated BCS superconductivity. We argue that the Ω-deformed gauge theory manifests the interesting cyclic RG behavior with the period of the RG cycle proportional to ε^{-1}. The deformed gauge theory can develop several non-perturbative scales. We conjecture on the monopole bound state interpretation of the Efimov tower.
