Localized Electrons

We study the momentum distribution of the electrons in an extended periodic Anderson model, where the interaction,Ucf, between itinerant and localized electrons is taken into account. In the symmetric half-filled model, due to the increase of the interorbital interaction, thefelectrons become more and more delocalized, while the itinerancy of conduction electrons decreases. Above a certain value ofUcfthefelectrons become again localized together with the conduction electrons. In the less than half-filled case, we observe thatUcfcauses strong correlations between thefelectrons in the mixed valence regime.

In this paper, we study the one-dimensional periodic Anderson model via bosonization. In the Toulouse limit, an effective Hamiltonian for the correlated electrons is derived. The effective Hamiltonian provides new information in understanding the emergence of ferromagnetism in the model.

Many rare earth and actinide intermetallics, known as Heavy Fermion Systems, have recently been successfully described by the Periodic Anderson Model. We investigate, in this work, various electronic and magnetic properties of the one-dimensional Periodic Anderson model using path integral formulation along with the quantum Monte Carlo simulation technique. We have studied the singlet and triplet pairing correlation functions, nearest neighbor charge-density correlations, spin density correlations, local squared magnetic moment and probability of double occupancy of f-electrons, as a function of intra-atomic Coulomb interaction for various values of hybridization parameter and the temperatures.
