The model is solved by using the dynamical mean-field theory combined with the exact diagonalization method. The heavy fermion state with large e ective mass due to the electron-phonon coupling is realized in the wide range of the f-electron number nf , while that due to the Coulomb interaction is realized in the narrow range of nf ~ 1.}, pages = {419--421}, title = {Heavy Fermion State in the Periodic Anderson-Holstein Model away from Half Filling}, volume = {310}, year = {2007} }
