Fictive Impurity Models: an Alternative Formulation of the Cluster Dynamical Mean Field Method
S. Okamoto, A. J. Millis, H. Monien +2
"Cluster" extensions of the dynamical mean field method to include longer range correlations are discussed. It is argued that the clusters arising in these methods are naturally in…
Strain selection of charge and orbital ordering patterns in half-doped manganites
M. J. Calderon, A. J. Millis, K. H. Ahn
Theoretical and computational results are presented clarifying the role of long-ranged strain interactions in determining the charge and orbital ordering in colossal magnetoresista…
Substrate-induced strain effects on Pr_{0.6}Ca_{0.4}MnO_{3} films
C. S. Nelson, J. P. Hill, Doon Gibbs +11
We report the characterization of the crystal structure, low-temperature charge and orbital ordering, transport, and magnetization of Pr_{0.6}Ca_{0.4}MnO_{3} films grown on LaAlO_{…
Quasiparticles in high temperature superconductors: consistency of angle resolved photoemission and optical conductivity
A. J. Millis, H. D. Drew
The consistency of angle-resolved photoemission and optical conductivity experiments on high temperature superconductors is examined. In the limit (apparently consistent with angle…
Towards a Classification of the Effects of Disorder on Materials Properties
A. J. Millis
Many 'interesting; correlated electron materials exhibit an unusual sensitivity of measured properties to external perturbations, and in particular to imperfections in the sample b…
