Exact results for the one dimensional periodic Anderson model at finite U

Abstract

We present exact results for the periodic Anderson model for finite Hubbard interaction 0 <= U < +infinity on certain restricted domains of the model's phase diagram, in d=1 dimension. Decomposing the Hamiltonian into positive semidefinite terms we find two quantum states to be ground state, an insulating and a metallic one. The ground state energy and several ground state expectation values are calculated.

Exact results for the one-dimensional periodic Anderson model at finite U

Iván Orlik, Zsolt Gulácsi

We present exact results for the periodic Anderson model for finite Hubbard interaction 0 < U < on certain restricted domains of the model's phase diagram, in d = 1 dimension. Decomposing the Hamiltonian into positive semidefinite terms we find two auantum states to be ground states; a completely localized ground state and a non-localized ground state. The ground-state energy and several ground-state expectation values were calculated.

Exact Insulating and Conducting Ground States of a Periodic Anderson Model in Three Dimensions

Zsolt Gulácsi, D. Vollhardt

We present a class of exact ground states of a three-dimensional periodic Anderson model at 3/4 filling. Hopping and hybridization of d and f electrons extend over the unit cell of a general Bravais lattice. Employing novel composite operators combined with 55 matching conditions the Hamiltonian is cast into positive semidefinite form. A product wave function in position space allows one to identify stability regions of an insulating and a conducting ground state. The metallic phase is a non-Fermi liquid with one dispersing and one flat band.

Exact results for the extended Anderson model with Falicov-Kimball interactions

L. G. Sarasúa, M. A. Contínentino

We present exact results for the extended periodic Anderson model with Falicov-Kimball interactions in one dimension $(d=1).$ Ground-state energies and their corresponding wave functions are obtained for a restricted region of the parameter space of the model Hamiltonian. In particular, two ground states are obtained, one containing one electron per site and the other three electrons per site. The expectation values of the occupation numbers and of the excitonic correlation functions $〈{\mathrm{cf}}^{+}〉$ are calculated using the exact ground state wave functions. Finally we discuss the possibility of a ferroelectric ground state in the Falicov-Kimball model.

Exact results related to the periodic Anderson model in D » 1 dimensions

Iván Orlik, Zsolt Gulácsi

We present exact results related to the T = 0 phase diagram of the periodic Anderson model in the strong coupling U =infinity limit for D = 2,3 dimensions. In a restricted parameter region, a ground state with simple algebraic structure was deduced in both dimensions, and its region of existence was characterized by sufficient conditions. The quasiparticle creation operator that builds up the ground state wave function does not satisfy the standard fermionic anticommutation relations.

Exact ground state for the generic periodic Anderson model around half-filling

Zsolt Gulácsi

Explicitly given, exact, ground-state solutions are reported for the one-dimensional periodic Anderson model in the limit of strong on-site repulsion, at and above half-filling, in the generic case of the model, for which f-electron hopping is forbidden. The description is presented for Bravais lattices, and the deduction procedure is based on decomposition of the starting Hamiltonian in positive semidefinite operators, which are defined as combinations of fermionic operators acting on the lattice sites of blocks. In comparison with the previously used procedures of this type, we use blocks greater than a unit cell, and a nonlinear combination of fermionic operators acting on the lattice sites. Based on such block operators, the previously known exact, ground-state solution possibilities at one-quarter and three-quarter filling have been extended to half-filling. The deduced ground state is present in restricted regions of the T = 0 phase diagram of the model, and is a spin-singlet conducting state.
