Arbitrary Choice of Basic Variables in Density Functional Theory. II. Illustrative Applications [PDF]

, 2003
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.

Quantum many-body dynamics in a Lagrangian frame: II. Geometric formulation of time-dependent density functional theory

, 2005
We formulate equations of time-dependent density functional theory (TDDFT) in the co-moving Lagrangian reference frame. The main advantage of the Lagrangian description of many-body dynamics is that in the co-moving frame the current density vanishes ...

The Potential-Density Phase Shift Method for Determining the Corotation Radii in Spiral and Barred Galaxies [PDF]

, 2006
We have developed a new method for determining the corotation radii of density waves in disk galaxies, which makes use of the radial distribution of an azimuthal phase shift between the potential and density wave patterns.

The wide variation of amazonian stocked hardwoods affecting natural resistance to arboreal termites over time

Maderas: Ciencia y Tecnología
After forest suppression in mining areas, deterioration of stocked tropical hardwoods occurs at different rates and levels. Prioritizing logs to avoid wastage is challenging because the wide interspecific variability of wood traits makes natural ...
