内容記述 | We investigate the electronic state of the periodic Anderson-Holstein model, which includes both the electron-electron Coulomb interaction and the electron-phonon coupling, away from half filing. 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. | |||||
