      abstract     = {We investigate, with the aid of numerical renormalization
                      group techniques, the thermoelectric properties of a
                      molecular quantum dot described by the negative-U Anderson
                      model. We show that the charge Kondo effect provides a
                      mechanism for enhanced thermoelectric power via a
                      correlation-induced asymmetry in the spectral function close
                      to the Fermi level. We show that this effect results in a
                      dramatic enhancement of the Kondo-induced peak in the
                      thermopower of negative-U systems with Seebeck coefficients
                      exceeding 50 mu V/K over a wide range of gate voltages.},
