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…
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…
Collective Directional Locking of Colloidal Monolayers on a Periodic Substrate
Ralph L. Stoop, Arthur V. Straube, Tom H Johansen +1
We investigate the directional locking effects that arise when a monolayer of paramagnetic colloidal particles is driven across a triangular lattice of magnetic bubbles. We use an…
Enhancing nanoparticle diffusion on a unidirectional domain wall magnetic ratchet
Ralph L. Stoop, Arthur V. Straube, Pietro Tierno
The performance of nanoscale magnetic devices is often limited by the presence of thermal fluctuations, while in micro-nanofluidic applications the same fluctuations may be used to…
