Query: Heat current in parametric quantum pump   We investigate the heat flow in the parametric quantum pump. Using the time
dependent scattering matrix theory, we have developed a general theory for the
pumped heat current at finite pumping amplitude and frequency. We have applied
our theory to a double barrier structure and studied pumped heat current in
both the weak and strong pumping regimes as different system parameters vary.
By comparing the pumped heat current and the power of Joule heat generated in
the system, we found that the double barrier structure can function as an
optimal pump in the strong pumping regime.
