Research activities (and some publications)

Molecular simulations in soft matter physics

Review of Monte Carlo simulation of coarse-grained polymer models [J. Baschnagel, J. P. Wittmer, H. Meyer (NIC Series 23, 83 (2004)]
Analysis of the dynamical properties of the slithering snake algorithm and a numerical test of the activated reptation hypothesis [L. Mattioni et al., Eur. Phys. J. E 10, 369 (2003)]

Conformation, structure and dynamics of polymer solutions and melts

In polymer melts excluded volume interactions are not screened down to the monomer scale. They lead to long-range correlations and so to corrections to chain ideality [J. P. Wittmer et al., Phys. Rev. E 76, 011803 (2007)]
In polymer melts hydrodynamic interactions are not screened for all times: Mediated by the melt’s viscoelasticity these interactions impact the polymer dynamics [J. Farago et al., Phys. Rev. E 85, 051807 (2012); J. Phys.: Condens. Matter 24, 284105 (2012)]
MD simulations verify that self-avoiding chains in strictly two-dimensional melts are segregated and compact, and have a fractal boundary [H. Meyer et al., J. Chem. Phys. 132, 184904 (2010)]

Slow dynamics in supercooled polymer melts and other complex liquids

Dynamic heterogeneities and higher-order correlation functions: In a polymer melt the range of correlated motion of the monomers grows on cooling towards the glass transition [C. Bennemann et al., Nature 399, 246 (1999)]
Extension of idealized mode-coupling theory to polymer melts and ab-initio comparison with MD simulations [S.-H. Chong et al., Phys. Rev. E 76, 051806 (2007) ; S. Frey et al., Eur. Phys. J. E 38, 11 (2015)]
At low temperatures monomers display jump-like motion which can be analyzed in terms of continuous-time random walks: methodology, mean-square displacement, van Hove correlation function [J. Helfferich et al., Phys. Rev. E 89, 042603 (2014); Phys. Rev. E 89, 042604 (2014); Eur. Phys. J. E 41, 71 (2018)]
The Voronoi binary liquid - a model for a simple fluid whose interactions are defined in terms of the Voronoi cells of the configurations and are thus local and many-body: Structural properties, glassy dynamics, and composition fluctuations [C. Ruscher et al., Phys. Rev. E 97, 032132 (2018); J. Phys.: Condens. Matter 33, 064001 (2021)]
A two-dimensional polydisperse glass-forming Lennard-Jones system: Analysis, by theory, MD and Monte simulations, shows that for this isotopic, achiral, equilibrium system the spatial correlations of the stress tensor [L. Klochko et al., J. Chem. Phys. 156, 164505 (2022); J. Wittmer et al., Phys. Rev. E 108, 015002 (2023)] and of the strain tensor [J. Wittmer et al., Soft Matter 19, 6140 (2023)] become long-ranged when elasticity emerges upon cooling to low temperature

Mechanical and viscoelastic properties of amorphous systems

Mechanical behavior of linear amorphous polymers: Comparison between molecular dynamics and finite-element simulations [M. Solar et al., Phys. Rev. E 85, 021808 (2012)]
Shear modulus in simple glass formers, isotropic networks and polymer glasses: Application of the stress-fluctuation formalism and relation to the shear relaxation modulus, effects of temperature and sampling time [J. P. Wittmer et al., J. Chem. Phys. 138, 12A533 (2013); I. Kriuchevskyi et al., Phys. Rev. E. 97, 012502 (2018); L. Klochko et al., J. Chem. Phys. 151, 054504 (2019)]
Shear stress relaxation in self-assembled transient networks : A simple model for "vitrimers" [J. P. Wittmer et al., Phys. Rev. E 93, 062611 (2016)]

Polymers at interfaces

MD results on the pressure tensor of polymer films [F. Varnik, J. Baschnagel, K. Binder, J. Chem. Phys. 113, 4444 (2000)]
Concentrated polymer solutions in a thin-film geometry : From equilibrium properties to solvent evaporation [S. Peter, H. Meyer, J. Baschnagel, J. Chem. Phys. 131, 014902 (2009) ; J. Chem. Phys. 131, 014903 (2009)]
Frictional forces and shear thinning in compressed nonentangled polymer brushes : Scaling theory, MD simulations and comparison to experiment [A. Galuschko et al., Langmuir 26, 6418 (2010)]
Molecular dynamics simulations show that viscoelastic effects are important to understand the capillary leveling of a step of a thin polymer film on an underlayer of the same polymer material [I. Tanis et al. J. Chem. Phys. 146, 203327 (2017)]

Polymer crystallization

On the role of short chain branches (SCBs) in crystalline model polyethylenes: lamella thickness decreases systematically with both faster cooling and increasing SCB content [W. S. Fall et al., Macromolecules 55, 8438 (2022)]
By adapting the experimental technique of “self-seeding” to simulations it is possible to grow unprecedentedly large polymer crystals in simulation and to unveil the crucial role played by chain branching to control the crystalline structure [W. S. Fall et al., ACS Macro Lett. 12, 808 (2023)]
