Magnetic field induced two-channel Kondo effect in multiple quantum dots

We study the possibility of observing the two-channel Kondo physics in multiple planar quantum dot heterostructures in the presence of a strong in-plane magnetic field. We show that a fine tuning of the coupling parameters of the system and an external magnetic field may stabilize the two-channel Kondo critical point. We make predictions for the behavior of the scaling of the differential conductance in the vicinity of the quantum critical point, as a function of magnetic field, temperature, and source-drain potential.
