Interfacial mobility in glass-forming polymer films: Is it determined by collective motion or intramolecular energetics?
Molecular simulations of glass-forming polymer films widely use generic models. As in simple liquids, these models assume intermolecular packing constraints as the dominant driving force for the glass transition. This view was seriously challenged by recent simulations of an atomistic model, suggesting that intramolecular barriers have a nonpertubative effect. To clarify this issue we propose a systematic simulation study allowing to interpolate between atomistic and generic models. Molecular dynamics simulations will use standard software as Lammps or Gromacs, but data analysis will need programming of new tools in C, C++ or Python.
The candidate should have a solid background in statistical physics and some programming experience.
The project will be performed in the Group Theory and Simulation of Polymers at Institut Charles Sadron in Strasbourg (France) with H. Meyer, M. Solar and J. Baschnagel in collaboration with Prof. W. Paul, Group of Theoretical Polymer Physics at University of Halle (Germany). The candidate will be enrolled for PhD in Strasbourg and paid with a regular french doctoral researcher contract. Extended stays in Halle are envisaged (with support of the French-German University DFH/UFA) and the possibility of cotutelle de these will be offered.
