Current-density functional theory for bosonic superfluids

open access: yesJournal of Physics Communications, 2023
A finite-temperature current-density functional theory for bosonic superfluids (sf-CDFT) in the thermal equilibrium state is proposed herein. In the sf-CDFT, hydrodynamic physical quantities, such as particle number density, current density, and the ...

Classical dynamical density functional theory: from fundamentals to applications [PDF]

open access: yesAdvances in Physics, 2020
Classical dynamical density functional theory (DDFT) is one of the cornerstones of modern statistical mechanics. It is an extension of the highly successful method of classical density functional theory (DFT) to nonequilibrium systems.

Density functional theory of electrowetting [PDF]

open access: yesPhysical Review E, 2014
The phenomenon of electrowetting, i.e., the dependence of the macroscopic contact angle of a fluid on the electrostatic potential of the substrate, is analyzed in terms of the density functional theory of wetting. It is shown that electrowetting is not an electrocapillarity effect, i.e., it cannot be consistently understood in terms of the variation of
