Query: Analytic treatment of the thermoelectric properties for two coupled
  quantum dots threaded by magnetic fields   Coupled double quantum dots (c-2QD) connected to leads have been widely
adopted as prototype model systems to verify interference effects on quantum
transport at the nanoscale. We provide here an analytic study of the
thermoelectric properties of c-2QD systems pierced by a uniform magnetic field.
Fully analytic and easy-to-use expressions are derived for all the kinetic
functionals of interest. Within the Green 0 s function formalism, our results
allow a simple inexpensive procedure for the theoretical description of the
thermoelectric phenomena for different chemical potentials and temperatures of
the reservoirs, different threading magnetic fluxes, dot energies and interdot
interactions; moreover they provide an intuitive guide to parametrize the
system Hamiltonian for the design of best performing realistic devices. We have
found that the thermopower S can be enhanced by more than ten times and the
figure of merit ZT by more than hundred times by the presence of a threading
magnetic field. Most important, we show that the magnetic flux increases also
the performance of the device under maximum power output conditions.
