Interplay between electronic and lattice superstructures in LaCaCuO
S. Hameed, Y. Liu, K. S. Rabinovich +11
Complex oxides are well known to develop oxygen ordering patterns with well defined periodicities, but their interplay with electronic correlations remains largely unexplored. Here…

Arbitrary Choice of Basic Variables in Density Functional Theory. II. Illustrative Applications
K. Higuchi, M. Higuchi
Our recent theory (Ref. 1) enables us to choose arbitrary quantities as the basic variables of the density functional theory. In this paper we apply it to several cases. In the cas…

Arbitrary Choice of Basic Variables in Density Functional Theory. I. Formalism
M. Higuchi, K. Higuchi
The Hohenberg-Kohn theorem of the density functional theory is extended by modifying the Levy constrained-search formulation. The new theorem allows us to choose arbitrary physical…
