Classical dynamical density functional theory: from fundamentals to applications

M te Vrugt, H Löwen, R Wittkowski - Advances in Physics, 2020 - Taylor & Francis
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 …

Semiflexible polymers in the bulk and confined by planar walls

SA Egorov, A Milchev, K Binder - Polymers, 2016 - mdpi.com
Semiflexible polymers in solution under good solvent conditions can undergo an isotropic-
nematic transition. This transition is reminiscent of the well-known entropically-driven …

Defying the gibbs phase rule: Evidence for an entropy-driven quintuple point in colloid-polymer mixtures

VFD Peters, M Vis, ÁG García, HH Wensink… - Physical Review Letters, 2020 - APS
Using a minimal algebraic model for the thermodynamics of binary rod-polymer mixtures, we
provide evidence for a quintuple phase equilibrium; an observation that seems to be at odds …
