Weakly interacting Bose gas in the vicinity of the critical point [PDF]
, 2004 We consider a three-dimensional weakly interacting Bose gas in the fluctuation region (and its vicinity) of the normal-superfluid phase transition point.

Density-Matrix functional theory of strongly-correlated lattice fermions
, 2002 A density functional theory (DFT) of lattice fermion models is presented, which uses the single-particle density matrix gamma_{ij} as basic variable. A simple, explicit approximation to the interaction-energy functional W[gamma] of the Hubbard model is ...

Compression wood in Pinus radiata II: Density and chemical composition
Maderas: Ciencia y Tecnología, 2014 Ten 22 year old radiata pine trees growing in two stands in Chile, one in clay and the other in humid sand soils showing some lean, were assessed for chemical composition and wood density of compres-sion wood. Signifi cant differences in type of wood in

Densities and energies of nuclei in dilute matter
, 2013 We explore the ground-state properties of nuclear clusters embedded in a gas of nucleons with the help of Skyrme-Hartree-Fock microscopic calculations. Two alternative representations of clusters are introduced, namely coordinate-space and energy-space ...

On geoclimatic variation in basic density of Scots pine wood.
Silva Fennica, 1979 The effect of temperature and water supply in the basic density of Scots pine ( L.) wood was studied on the basis of material obtained from the literature.

Density-functional theory with additional basic variables: Extended Legendre transform
Physical Review A, 2009 In a recent series of papers, Higuchi and Higuchi defined an extended constrained-search procedure by extending the Levy constrained search by adding additional constraints. As shown here, this procedure can be equivalently formulated in terms of Lieb's Legendre transformation functional.
