Periodic Anderson model with electron-phonon correlated conduction band
Peng Zhang, Peter Reis, Ka-Ming Tam +4
This paper reports dynamical mean field calculations for the periodic Anderson model in which the conduction band is coupled to phonons. Motivated in part by recent attention to th…
The screening of 4f moments and delocalization in the compressed light rare earths
A. K. McMahan, R. T. Scalettar, M. Jarrell
Spin and charge susceptibilities and the 4f^n, 4f^{n-1}, and 4f^{n+1} configuration weights are calculated for compressed Ce (n=1), Pr (n=2), and Nd (n=3) metals using dynamical me…
Charge Fluctuations and the Valence Transition in Yb under Pressure
E. R. Ylvisaker, J. Kuneš, A. K. McMahan +1
We present a dynamical mean field theory study of the valence transition () in elemental, metallic Yb under pressure. Our calculations reproduce the observed val…
Spectral Properties of delta-Plutonium: Sensitivity to 5f Occupancy
Jian-Xin Zhu, A. K. McMahan, M. D. Jones +4
By combining the local density approximation (LDA) with dynamical mean field theory (DMFT), we report a systematic analysis of the spectral properties of -plutonium with varying…
Combined local-density and dynamical mean field theory calculations for the compressed lanthanides Ce, Pr, and Nd
A. K. McMahan
This paper reports calculations for compressed Ce (4f^1), Pr (4f^2), and Nd (4f^3) using a combination of the local-density approximation (LDA) and dynamical mean field theory (DMF…
Thermodynamic and spectral properties of compressed Ce calculated by the merger of the local density approximation and dynamical mean field theory
A. K. McMahan, K. Held, R. T. Scalettar
We have calculated thermodynamic and spectral properties of Ce metal over a wide range of volume and temperature, including the effects of 4f electron correlations, by the merger o…
The LDA+DMFT Approach to Materials with Strong Electronic Correlations
K. Held, I. A. Nekrasov, G. Keller +7
LDA+DMFT is a novel computational technique for ab initio investigations of real materials with strongly correlated electrons, such as transition metals and their oxides. It combin…
Doping-dependent study of the periodic Anderson model in three dimensions
Thereza Paiva, Gokhan Esirgen, Richard T. Scalettar +2
We study a simple model for -electron systems, the three-dimensional periodic Anderson model, in which localized states hybridize with neighboring states. The states…
The Cerium volume collapse: Results from the LDA+DMFT approach
K. Held, A. K. McMahan, R. T. Scalettar
The merger of density-functional theory in the local density approximation (LDA) and many-body dynamical mean field theory (DMFT) allows for an ab initio calculation of Ce includin…
Signatures of Spin and Charge Energy Scales in the Local Moment and Specific Heat of the Two-Dimensional Hubbard Model
Thereza Paiva, R. T. Scalettar, Carey Huscroft +1
Local moment formation driven by the on--site repulsion is one of the most fundamental features in the Hubbard model. At the simplest level, the temperature dependence of the l…
Similarities between the Hubbard and Periodic Anderson Models at Finite Temperatures
K. Held, C. Huscroft, R. T. Scalettar +1
The single band Hubbard and the two band Periodic Anderson Hamiltonians have traditionally been applied to rather different physical problems - the Mott transition and itinerant ma…
Magnetic and Thermodynamic Properties of the Three-Dimensional Periodic Anderson Hamiltonian
Carey Huscroft, A. K. McMahan, R. T. Scalettar
The three dimensional periodic Anderson model is studied with Quantum Monte Carlo. We find that the cross-over to the Kondo singlet regime is remarkably sharp at low temperatures,…
Volume-Collapse Transitions in the Rare Earth Metals
A. K. McMahan, C. Huscroft, R. T. Scalettar +1
We describe current experimental and theoretical understanding of the pressure-induced volume collapse transitions occurring in the early trivalent rare earth metals. General featu…
