Research interests (and some selected publications)

  • Molecular simulation of soft matter systems
    • Monte Carlo simulation of coarse-grained polymer models [J. Baschnagel, J. P. Wittmer, H. Meyer, (NIC Series 23, 83 (2004)]
    • 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 and lead to long-range correlations [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)]
    • 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)]
  • Glassy dynamics of supercooled polymer melts
  • Mechanical and viscoelastic properties of amorphous solids
    • 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. Lett. 119, 147802 (2017)]
    • 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
