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…
Photocatalytic magnetic microgyroscopes with activity-tunable precessional dynamics
Dolachai Boniface, Arthur V. Straube, Pietro Tierno
Magnetic nano/microrotors are passive elements that spin around an axis due to an external rotating field while remaining confined to a close plane. They have been used to date in…
Memory effects in colloidal motion under confinement and driving
Arthur V. Straube, Felix Höfling
The transport of individual particles in inhomogeneous environments is complex and exhibits non-Markovian responses. The latter may be quantified by a memory function within the fr…
Langevin equations and a geometric integration scheme for the overdamped limit of rotational Brownian motion of axisymmetric particles
Felix Höfling, Arthur V. Straube
The translational motion of anisotropic or self-propelled colloidal particles is closely linked with the particle's orientation and its rotational Brownian motion. In the overdampe…
Excluded Volume Induces Buckling in Optically Driven Colloidal Rings
Eric Cereceda-Lóopez, Mattia Ostinato, Antonio Ortiz-Ambriz +3
In our combined experimental, theoretical and numerical work, we study the out of equilibrium deformations in a shrinking ring of optically trapped, interacting colloidal particles…
Depinning transition of self-propelled particles
Arthur V. Straube, Felix Höfling
Depinning transitions occur when a threshold force must be applied to drive an otherwise immobile system. For the depinning of colloidal particles from a corrugated landscape, we s…
