Microscopic derivation of the thin film equation using the Mori-Zwanzig formalism
Michael te Vrugt, Leon Topp, Raphael Wittkowski +1
The hydrodynamics of thin films is typically described using phenomenological models whose connection to the microscopic particle dynamics is a subject of ongoing research. Existin…

Wetting dynamics under periodic switching on different scales: Characterization and mechanisms
Leon Topp, Moritz Stieneker, Svetlana Gurevich +1
The development of substrates with a switchable wettability is on a fast pace. The limit of switching frequencies and contact angle differences between substrate states are steadil…

Multiscale perspective on wetting on switchable substrates: mapping between microscopic and mesoscopic models
Moritz Stieneker, Leon Topp, Svetlana Gurevich +1
To understand the non-equilibrium relaxation dynamics of a liquid droplet on a switchable substrate the interplay of different length- and time-scales needs to be understood. We pr…
