      abstract     = {The t(2g) quasiparticle spectra of Na0.3CoO2 are calculated
                      within the dynamical mean field theory. It is shown that as
                      a result of dynamical Coulomb correlations charge is
                      transferred from the nearly filled e(g)(') subbands to the
                      a(1g) band, thereby reducing orbital polarization among Co
                      t(2g) states. Dynamical correlations therefore stabilize the
                      small e(g)(') Fermi surface pockets, in contrast to
                      angle-resolved photoemission data, which do not reveal these
                      pockets.},
