Simplified periodic Anderson model: Exact solution in infinite dimensions
We present a diagrammatic perturbative treatment of the hybridization for the periodic Anderson model that recovers the dynamical mean-field equations in the limit of infinite dimensions. The resulting effective singlesite problem is naturally addressed by perturbation theory on the dynamical mean field. We introduce a simplified version of the model in which only electrons with a given spin or...
متن کاملExact ground states of the periodic Anderson model in D=3 dimensions
We construct a class of exact ground states of three-dimensional periodic Anderson models PAMs , including the conventional PAM, on regular Bravais lattices at and above 3/4 filling, and discuss their physical properties. In general, the f electrons can have a weak dispersion, and the hopping and the nonlocal hybridization of the d and f electrons extend over the unit cell. The construction is ...
متن کاملExact insulating and conducting ground states of a periodic Anderson model in three dimensions.
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 ide...
متن کاملAn Exact Solution of Gauged Thirring Model in Two Dimensions ∗
In two space-time dimensions, we write down the exact and closed Schwinger-Dyson equation for the gauged Thirring model which has been proposed recently by the author. The gauged Thirring model is a natural gauge-invariant extension of the Thirring model and reduces to the Schwinger model (in the Abelian case) in the strong four-fermion coupling limit. The exact SD equation is derived by making...
متن کاملProtracted screening in the periodic Anderson model
The asymmetric infinite-dimensional periodic Anderson model is examined with a quantum Monte Carlo simulation. For small conduction band filling, we find a severe reduction in the Kondo scale, compared to the impurity value, as well as protracted spin screening consistent with some recent controversial photoemission experiments. The Kondo screening drives a ferromagnetic transition when the con...
