Mott transition of the f-electron system in the periodic Anderson model with nearest neighbor hybridization

Abstract

We show analytically that, under certain assumptions, the periodic Anderson model and the Hubbard model become equivalent within the dynamical mean field theory for quasiparticle weight Z -> 0. A scaling relation is derived which is validated numerically using the numerical renormalization group at zero temperature and quantum Monte Carlo simulations at finite temperatures. Our results show that the f-electrons of the half-filled periodic Anderson model with nearest neighbor hybridization get localized at a finite critical interaction strength U_c}, also at zero temperature. This transition is equivalent to the Mott-transition in the Hubbard model.
