Query: Particle-conserving dynamics on the single-particle level   We generalize the particle-conserving dynamics method of de las Heras et al.
[J. Phys. Condens. Matter: 28, 24404 (2016).] to binary mixtures and apply this
to hard rods in one dimension. Considering the case of one species consisting
of only one particle enables us to address the tagged-particle dynamics. The
time-evolution of the species-labeled density profiles is compared to exact
Brownian dynamics and (grand-canonical) dynamical density functional theory.
The particle conserving dynamics yields improved results over the dynamical
density functional theory and well reproduces the simulation data at short and
intermediate times. However, the neglect of a strict particle order (due to the
fundamental statistical assumption of ergodicity) leads to errors at long times
for our one-dimensional setup. The isolated study of that error makes clear the
fundamental limitations of (adiabatic) density-based theoretical approaches
when applied to systems of any dimension for which particle caging is a
dominant physical mechanism.
