Dynamical modes of sheared confined microscale matter
Sascha Gerloff, Antonio Ortiz-Ambriz, Pietro Tierno +1
Based on (overdamped) Stokesian dynamics simulations and video microscopy experiments, we study the non equilibrium dynamics of a sheared colloidal cluster, which is confined to a…
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…
Propulsion and energetics of a minimal magnetic microswimmer
Carles Calero, José García-Torres, Antonio Ortiz-Ambriz +3
In this manuscript we describe the realization of a minimal hybrid microswimmer, composed of a ferromagnetic nanorod and a paramagnetic microsphere. The unbounded pair is propelled…
Topology Restricts Quasidegeneracy in Sheared Square Colloidal Ice
Erdal C. Oğuz, Antonio Ortiz-Ambriz, Hadas Shem-Tov +3
Recovery of ground-state degeneracy in two-dimensional square ice is a significant challenge in the field of geometric frustration with far-reaching fundamental implications, such…
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…
