Dynamics and Clogging of colloidal monolayers magnetically driven through an heterogeneous landscape
Sergi Granados Leyva, Ralph Lukas Stoop, Pietro Tierno +1
We combine experiments and numerical simulations to investigate the emergence of clogging in a system of interacting paramagnetic colloidal particles driven against a disordered la…
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…
Clogging and Jamming of Colloidal Monolayers Driven Across a Disordered Landscape
Ralph L. Stoop, Pietro Tierno
We experimentally investigate the clogging and jamming of interacting paramagnetic colloids driven through a quenched disordered landscape of fixed obstacles. When the particles ar…
