Fluid structure from density-functional theory

We treat various common fluid models, like the inverse-power, Asakura-Oosawa, and Lennard-Jones potentials, within the soft fundamental measure theory (SFMT). We show that this recently proposed density-functional approach is able to predict the pair correlations in the fluid phase reliably compared to computer simulations. Explicit expressions for certain quantities of SFMT are given, namely, ...

From Density Functional Theory to Density Matrix Functional Theory

Coupled cluster methods are considered among the most accurate tools in electronic structure theory. Nonetheless relatively limited attempt seems to have been made to extend their applicability to the description of the core-excitation phenomena that are behind largely used spectroscopic techniques like x-ray absorption spectroscopy and x-ray circular dichroism. As a first step to redeem for su...

Dynamics of localized particles from density functional theory.

A fundamental assumption of the dynamical density functional theory (DDFT) of colloidal systems is that a grand-canonical free-energy functional may be employed to generate the thermodynamic driving forces. Using one-dimensional hard rods as a model system, we analyze the validity of this key assumption and show that unphysical self-interactions of the tagged particle density fields, arising fr...

Spin dynamics from time-dependent spin-density-functional theory.

We derive the spin-wave dynamics of a magnetic material from the time-dependent spin-density-functional theory in the linear response regime. The equation of motion for the magnetization includes, besides the static spin stiffness, a "Berry curvature" correction and a damping term. A gradient expansion scheme based on the homogeneous spin-polarized electron gas is proposed for the latter two qu...
