  At low temperatures, a system built from a small droplet of electrons and a
larger, but still finite, droplet may display non-Fermi-liquid behavior.
Stabilization of a multi-channel Kondo fixed point requires fine control of the
electrochemical potential in each droplet. The desired fine control can be
achieved by adjusting voltages on nearby gate electrodes. We study the
conditions for obtaining this type of non-Fermi-liquid behavior and discuss the
experimentally-observable consequences.
