A geometry-based model for spreading drops applied to drops on a silicon wafer and a swellable polymer brush film
Mathis Fricke, Beatrice Fickel, Maximilian Hartmann +3
We investigate the dynamics of spreading in a regime where the shape of the drop is close to a spherical cap. The latter simplification is applicable in the late (viscous) stage of…
Breakup Dynamics of Capillary Bridges on Hydrophobic Stripes
Maximilian Hartmann, Mathis Fricke, Lukas Weimar +4
The breakup dynamics of a capillary bridge on a hydrophobic stripe between two hydrophilic stripes is studied experimentally and numerically using direct numerical simulations. The…
The interaction of inner and outer surface corners during spontaneous wetting
Felix Gerlach, Maximilian Hartmann, Cameron Tropea
Real world surfaces can often be modeled as a collection of edges, corners, dents or spikes of varying roundness. These features exhibit individual spontaneous wetting behaviors co…
Nonlinear coherence effects in transient-absorption ion spectroscopy with stochastic extreme-ultraviolet free-electron laser pulses
Thomas Ding, Marc Rebholz, Lennart Aufleger +21
We demonstrate time-resolved nonlinear extreme-ultraviolet absorption spectroscopy on multiply charged ions, here applied to the doubly charged neon ion, driven by a phase-locked s…
Strong-field extreme-ultraviolet dressing of atomic double excitation
Christian Ott, Lennart Aufleger, Thomas Ding +21
We report on the experimental observation of strong-field dressing of an autoionizing two-electron state in helium with intense extreme-ultraviolet laser pulses from a free-electro…
