      abstract     = {We investigate the effect of vibrational degrees of freedom
                      on the linear thermoelectric transport through a
                      single-level quantum dot described by the spinless
                      Anderson-Holstein impurity model. To study the effects of
                      strong electron-phonon coupling, we use the nonperturbative
                      numerical renormalization group approach. We also compare
                      our results, at weak to intermediate coupling, with those
                      obtained by employing the functional renormalization group
                      method, finding good agreement in this parameter regime.
                      When applying a gate voltage at finite temperatures, the
                      inelastic scattering processes, induced by phonon-assisted
                      tunneling, result in an interesting interplay between
                      electrical and thermal transport. We explore different
                      parameter regimes and identify situations for which the
                      thermoelectric power as well as the dimensionless figure of
                      merit are significantly enhanced via a Mahan-Sofo type of
                      mechanism. We show, in particular, that this occurs at
                      strong electron-phonon coupling and in the antiadiabatic
                      regime.},
