  • Asymptotic regimes in elastohydrodynamic and stochastic leveling on a viscous film 
    Pedersen, Christian; Niven, John; Dalnoki-Veress, Kari; Salez, Thomas; Carlson, Andreas (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)
    An elastic sheet that deforms near a solid substrate in a viscous fluid is a situation relevant to various dynamical processes in biology, geophysics, and engineering. Here, we study the relaxation dynamics of an elastic ...
  • Capillary deformation of ultrathin glassy polymer films by air nanobubbles 
    Ren, Shuai; Pedersen, Christian; Carlson, Andreas; Salez, Thomas; Wang, Yuliang (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Confined glasses and their anomalous interfacial rheology raise important questions in fundamental research and numerous practical applications. In this work, we study the influence of interfacial air nanobubbles on the ...
  • Nanobubble-induced flow of immersed glassy polymer films 
    Pedersen, Christian; Ren, Shuai; Wang, Yuliang; Carlson, Andreas; Salez, Thomas (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    We study the free-surface deformation dynamics of an immersed glassy thin polymer film supported on a substrate, induced by an air nanobubble at the free surface. We combine analytical and numerical treatments of the glassy ...
  • Near-critical spreading of droplets 
    Saiseau, Raphael; Pedersen, Christian; Benjana, Anwar; Carlson, Andreas; Delabre, Ulysse; Salez, Thomas; Delville, Jean-Pierre (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    Abstract We study the spreading of droplets in a near-critical phase-separated liquid mixture, using a combination of experiments, lubrication theory and finite-element numerical simulations. The classical Tanner’s law ...
  • Surface and bulk relaxation of vapor-deposited polystyrene glasses 
    Yin, Junjie; Pedersen, Christian; Thees, Michael F.; Carlson, Andreas; Salez, Thomas; Forrest, James A. (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2023)
    We have studied the liquid-like response of the surface of vapor-deposited glassy films of polystyrene to the introduction of gold nanoparticles on the surface. The build-up of polymer material was measured as a function ...
  • Universal self-similar attractor in the bending-driven levelling of thin viscous films 
    Pedersen, Christian; Salez, Thomas; Carlson, Andreas (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2021)
    We study theoretically and numerically the bending-driven levelling of thin viscous films within the lubrication approximation. We derive Green’s function of the linearized thin-film equation and further show that it ...
