  "abstract": "We study the Fano-Kondo effect in a closed Aharonov-Bohm (AB) interferometer which contains a single-level quantum dot and predict a frequency doubling of the AB oscillations as a signature of Kondo-correlated states. Using Keldysh formalism, Friedel sum rule and Numerical Renormalization Group, we calculate the exact zero-temperature linear conductance $G$ as a function of AB phase $\\phi$ and level position $\\epsilon$. In the unitary limit, $G(\\phi)$ reaches its maximum $2e^2/h$ at $\\phi=\\pi/2$. We find a Fano-suppressed Kondo plateau for $G(\\epsilon)$ similar to recent experiments.",
