Ferromagnetism in the Periodic Anderson Model: A Comparison of Spectral Density Approximation (SDA), Modified Alloy Analogy (MAA) and Modified Perturbation Theory (MPT)
D. Meyer, W. Nolting
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…
Ferromagnetism in the Periodic Anderson Model - a Modified Alloy Analogy
G G Reddy, D Meyer, S Schwieger +2
We introduce a new aproximation scheme for the periodic Anderson model (PAM). The modified alloy approximation represents an optimum alloy approximation for the strong coupling lim…
Dynamical mean-field study of ferromagnetism in the periodic Anderson model
D. Meyer, W. Nolting
The ferromagnetic phase diagram of the periodic Anderson model is calculated using dynamical mean-field theory in combination with the modified perturbation theory. Concentrating o…
Kondo screening and exhaustion in the periodic Anderson model
D. Meyer, W. Nolting
We investigate the paramagnetic periodic Anderson model using the dynamical mean-field theory in combination with the modified perturbation theory which interpolates between the we…
