Mean - field dynamical density functional theory
We examine the out-of-equilibrium dynamical evolution of density profiles of ultrasoft particles under time-varying external confining potentials in three spatial dimensions. The theoretical formalism employed is the dynamical density functional theory (DDFT) of Marini Bettolo Marconi and Tarazona [J. Chem. Phys. 110, 8032 (1999)], supplied by an equilibrium excess free energy functional that i...
متن کاملDerivation of a three-dimensional phase-field-crystal model for liquid crystals from density functional theory.
Using a generalized order-parameter gradient expansion within density functional theory, we derive a phase-field-crystal model for liquid crystals composed of apolar particles in three spatial dimensions. Both the translational density and the orientational direction and ordering are included as order parameters. Different terms involving gradients in the order parameters in the resulting free-...
متن کاملVacancy diffusion in colloidal crystals as determined by dynamical density-functional theory and the phase-field-crystal model.
A two-dimensional crystal of repulsive dipolar particles is studied in the vicinity of its melting transition by using Brownian dynamics computer simulation, dynamical density-functional theory, and phase-field-crystal modeling. A vacancy is created by taking out a particle from an equilibrated crystal, and the relaxation dynamics of the vacancy is followed by monitoring the time-dependent one-...
متن کاملPhase-space approach to dynamical density functional theory.
The authors consider a system of interacting particles subjected to Langevin inertial dynamics and derive the governing time-dependent equation for the one-body density. They show that, after suitable truncations of the Bogoliubov-Born-Green-Kirkwood-Yvon hierarchy, and a multiple time scale analysis, they obtain a self-consistent equation involving only the one-body density. This study extends...
متن کاملExact Double Counting in Combining the Dynamical Mean Field Theory and the Density Functional Theory.
We propose a continuum representation of the dynamical mean field theory, in which we were able to derive an exact overlap between the dynamical mean field theory and band structure methods, such as the density functional theory; double counting. The implementation of this exact double counting shows improved agreement between the theory and experiment in several correlated solids, such as the ...
