Energetic characterisation of transient clustering dynamics in aggregation-diffusion systems
Nathalie Wehlitz, Richard Scherzer, Carsten Hartmann +1
We investigate transient clustering dynamics in nonlocal aggregation-diffusion systems from an energetic perspective. Starting from a stochastic interacting particle system, we stu…

Unfolding the geometric structure and multiple timescales of the urea-urease pH oscillator
Arthur V. Straube, Guillermo Olicón Méndez, Stefanie Winkelmann +2
We study a two-variable dynamical system modeling pH oscillations in the urea-urease reaction within giant lipid vesicles -- a problem that intrinsically contains multiple, well-se…
