  We study the possibility to observe the two channel Kondo physics in multiple
quantum dot heterostructures in the presence of 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 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.
