Blocking transport resonances via Kondo many-body entanglement in quantum dots

The many-body Kondo effect manifests in low-temperature Coulomb blockaded quantum dots as a zero-bias conductance peak, which arises due to charge-fluctuation-driven transport. Here, the authors demonstrate a counterintuitive Kondo effect in which these conduction channels are blocked.
