Query: Multi-terminal far-from-equilibrium thermoelectric nano-devices in the
  Kondo regime   The quest for good thermoelectric materials and/or high-efficiency
thermoelectric devices is of primary importance from theoretical and practical
points of view. Low-dimensional structures with quantum dots or molecules are
promising candidates to achieve the goal. Interactions between electrons,
far-from-equilibrium conditions and strongly non-linear transport are important
factors affecting the usefulness of the devices. This paper analyses the
thermoelectric power of a two-terminal quantum dot under large thermal $\Delta
T$ and voltage $V$ biases as well as the performance of the three-terminal
system as a heat engine. To properly characterise the non-linear effects under
these conditions, two different Seebeck coefficients are introduced,
generalizing the linear response expression. The direct calculations of
thermally induced electric and heat currents show, in agreement with recent
work, that the efficiency of the thermoelectric heat engine as measured by the
delivered power is maximal far from equilibrium. Moreover, the strong Coulomb
interactions between electrons on the quantum dot are found to diminish the
efficiency at maximum power and the maximal value of the delivered power, both
in the Kondo regime and outside of it.
