Superadiabatic Dynamical Density Functional Theory for One-Dimensional Brownian Hard-Rod Fluids

We study the relaxation dynamics of a one-dimensional system of hard rods at the level of one-body fields using superadiabatic dynamical density functional theory, and compare the results with Brownian dynamics simulations. The theory uses the exact equilibrium excess free energy functional and incorporates superadiaba...

Cubic-Equivariant Neural Density Functional Theory for Three-Dimensional Lattice Fluids

A neural classical density functional that acts directly on unrestricted three-dimensional density profiles while also identifying accurate full-dimensional training data, thermodynamic consistency, and structural correlations as the central challenges for extensions to continuum fluids.
