C1: Using molecular fields to bridge between particle and continuum representations of macromolecular systems
The goal of this project is to use so-called “molecular field” models – which operate with continuous fields, but still retain explicit information on the molecular structure of materials - as bridges between particle-based and field-based views on macromolecular materials. In the first funding period, we have systematically compared the properties of particle models and established molecular field models, and derived different adaptive resolution schemes that combine the two representations. Building on this, we plan to (i) develop systematic methods for deriving dynamical molecular field models from particle simulations, (ii) further optimize the dynamical adaptive resolution schemes, and (iii) apply them to interesting materials such as transient networks.
