Quantum phase transition in a two-channel-Kondo quantum dot device
Quantum phase transition in a two-channel-Kondo quantum dot device
We develop a theory of electron transport in a double quantum dot device recently proposed for the observation of the two-channel Kondo effect. Our theory provides a strategy for tuning the device to the non-Fermi-liquid fixed point, which is a quantum critical point in the space of device parameters. We …
