Protracted 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...

Ferromagnetism in the Periodic Anderson Model

We compare different approximation schemes for investigating ferromagnetism in the periodic Anderson model. The use of several approximations allows for a detailed analysis of the implications of the respective methods, and also of the mechanisms driving the ferromagnetic transition. For the Kondo limit, our results confirm a previously proposed mechanism leading to ferromagnetic order, namely ...

Localized Entanglement in One-dimensional Anderson Model

Entanglement is a kind of nonlocal correlation that only exists in quantum systems. Recent studies on entanglement have been motivated by its potential applications in quantum computation, quantum teleportation and quantum communication. As the spin system is perfect to realize the quantum computer, many efforts focus on the entanglement in the Heisenberg spin model, Ising model in a transverse...

Bistability of anderson localized States in nonlinear random media.

We study wave transmission through one-dimensional random nonlinear structures and predict a novel effect resulting from an interplay of nonlinearity and disorder. We reveal that, while weak nonlinearity does not change the typical exponentially small transmission in the regime of the Anderson localization, it affects dramatically the disorder-induced localized states excited inside the medium ...

Exact 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 ...
