Pressure dependence of magnetic and superconducting transitions in sodium cobalt oxides NaxCoO2

Y. V. Sushko, O. B. Korneta, S. O. Leontsev +3

The results of DC magnetization measurements under hydrostatic (helium-gas) pressure are reported for an ambient pressure superconductor Na0.35CoO2.1.4D2O and its precursor compoun…

Two Quantum Cluster Approximations

Th. A. Maier, O. Gonzalez, M. Jarrell +1

We provide microscopic diagrammatic derivations of the Molecular Coherent Potential Approximation (MCA) and Dynamical Cluster Approximation (DCA) and show that both are Phi-derivab…

AB Initio Studies of Electronic Excitations in Real Solids

Adolfo G. Eguiluz, Wei Ku

The first part of this article centers on the fact that key features of the dynamical response of weakly-correlated materials (the alkalis, Al), have been found experimentally to d…

Dynamical Response of Correlated Electrons in Solids Probed by Inelastic Scattering Experiments: An Ab Initio Theoretical Perspective

Adolfo G. Eguiluz, Wei Ku, James M. Sullivan

We present results of ab initio theoretical investigations of the excitation spectra of correlated electrons in metals (Al, K, and Li) and their interplay with inelastic scattering…

Ab Initio Evaluation of Plasmon Lifetimes in the Alkali Metals

Wei Ku, Adolfo G. Eguiluz

The anomalous plasmon linewidth dispersion (PLD) measured in K by vom Felde, Sprosser-Prou, and Fink (Phys. Rev. B 40, 10181 (1989)), has been attributed to strong dynamical electr…
