In this paper, the history, present status, and future of density-functional theory (DFT) is
informally reviewed and discussed by 70 workers in the field, including molecular scientists …

We summarize the theory of van der Waals (dispersion) forces, with emphasis on recent
microscopic approaches that permit the prediction of forces between solids and …

The random-phase approximation (RPA) as an approach for computing the electronic
correlation energy is reviewed. After a brief account of its basic concept and historical …

Hydrodynamic flow occurs in an electron liquid when the mean free path for electron-
electron collisions is the shortest length scale in the problem. In this regime, transport is …

Time-dependent density functional theory continues to draw a large number of users in a
wide range of fields exploring myriad applications involving electronic spectra and …

We investigate the hydrodynamic theory of metals, offering systematic studies of the linear-
response dynamics for an inhomogeneous electron gas. We include the quantum functional …

The quantum hydrodynamic theory is a promising method for describing microscopic details
of macroscopic systems. The hydrodynamic equation can be partially obtained from a single …

The spatial distribution of the internal pressure of an electron fluid, which spontaneously
arises at the formation of a molecule or a crystal, is linked to the main features of chemical …

We derive a closed equation of motion for the current density of an inhomogeneous
quantum many-body system under the assumption that the time-dependent wave function …

By analyzing the breathing mode of a Bose-Einstein condensate repulsively interacting with
a polarized fermionic cloud, we further the understanding of a Bose-Fermi mixture recently …
