Query: Rescuing a Quantum Phase Transition with Quantum Noise   We show that placing a quantum system in contact with an environment can
enhance non-Fermi-liquid correlations, rather than destroy quantum effects as
is typical. The system consists of two quantum dots in series with two leads;
the highly resistive leads couple charge flow through the dots to the
electromagnetic environment, the source of quantum noise. While the charge
transport inhibits a quantum phase transition, the quantum noise reduces charge
transport and restores the transition. We find a non-Fermi-liquid intermediate
fixed point for all strengths of the noise. For strong noise, it is similar to
the intermediate fixed point of the two-impurity Kondo model.
