Quantum phase transition in a minimal model for the Kondo effect in a Josephson junction

Abstract

We propose a minimal model for the Josephson current through a quantum dot in a Kondo regime. We start with the model that consists of an Anderson impurity connected to two superconducting (SC) leads with the gaps ∆α = |∆α| eα , where α = L, R for the lead at left and right. We show that, when one of the SC gaps is much larger than the others |∆L| ≫ |∆R… (More)
